ekrn.exe at 99% CPU usage is Commodo Firewall Pro 3 the reason?

[enduser999]

I am using NOD32 V3 as well as Comodo Firewall Pro v3.0.13.268 and Process Manager shows 99% CPU by ekrn.exe! Is this a known problem?

[Ade 1]

I'm running both of these together and everything working perfectly. I also run Threatfire 3 too and no problems.

[Zarra]

enduser999, check this thread out for your problem.

Well I looked at that thread but seen no mention of ekrn.exe or am I missing something?

[Zarra]

I'm sorry about that. I seen high CPU usuage so I posted that link. I'll do some digging to see if I can find something for ekrn.exe.

[Nahaz]

I've noticed it too under Comodo.

I looked at my Windows Task Manager but I don't see it there at all but Comodo shows it as 99-100%

[SteveBlanchard]

Threatfire icaused my problem, when I installed CPF3 the PC went very slow, took off Threatfire and Hey Presto, no problem!
Using BOClean again.
I wonder whether the problem is the order that things are installed?

[Banger696]

I've just experienced this and I'm not using Comodo just Windows Firewall and a hardware firewall. ekrn.exe was at 100% and lagging my machine making doing things virtually impossible. Had to end the ekrn.exe task before it went back to normal CPU use. Is this a known problem?

[Ade 1]

Hi. I've just been playing COD4 online and had to quit out 'cos even though my ping was only about 50 I can experiencing freezes all the time lasting up to 10 secs at a time which is no good for online.

I quit out and noticed ekrn.exe running at 50%. Rebooted and it's back to normal. Not sure if that was the reason for the freezing as I've not experienced this before. Perhaps going back to 2.7 might solve my problem.

I upgraded to CFP v3 and saw the 99%, however CFP v3 didn't work out so I reverted back to CFP v2.4 and I still see the 99%.

I think the CFP is a red herring as I've experienced the problem without CFP.

[SteveBlanchard]

The only time I have seen 99% CPU power is with a scan running.

[sandman423]

Anyone figure this out yet??

Ekrn.exe is at 95% CPU Usage and I am using Nod32 v3 and CFP and A-Squared...


Please can someone figure this out please my computer is lagging especially online...

[Banger696]

Reboot or terminating ekrn.exe fixed it for me but it's not ideal.

[twl845]

I thoght I had it when I checked the scheduling page on NOD. I was able to uncheck a few options. Then I checked CFP 2.4 and 99% was gone. But I checked it a few minutes later and it was back.

[Banger696]

Tried a re-install ? Cleaning out the ESET folders and I haven't had a re-occurance yet. Suspect it has something to do with the update schedule as that is the only thing that has run since yesterday. My scheduled scan is set for the early hours of Tuesday so it's not that.

I watched it on the CFP screen. It's 2 minutes on, 2 minutes off.

How strange. :o

I sent a note to Eset support. Maybe they'll e-mail me a fix.

Let us know how you get on it's pointless us all emailing Eset. :thumb:

[twl845]

While I wait for Eset to answer my inquiry, I did a re-install for a couple of reasons and I notice the CPU usage for ekrn.exe fluctuates around 92% leaving 7% for other stuff rather than being pinned at 100%. hmmmm

[sandman423]

Well Here is the thing...

I noticed ekrn.exe was at 100% CPU Usage today and yesterday but two days ago it was at 37%...

Please explain how to fix it from being 100% when you hear from Esest...thanks

[Banger696]

I haven't had a repeat of the 100% yet since I re-installed.

I'm still waiting for a response from Eset. I guess they don't know yet, but I will definately post if and when they respond. Maybe if Everybody bombarded them they would get on it faster.:)

[twl845]

I received a response from Eset today as follows:
Hello,
To have a better chance at seeing what it may be, please send us the logs from these utilities.
HijackThis:
Download program from http://nod32-av.com/utilities/hijackthis%20for%20troubleshooting/hijackthis.exe

The Belarc advisor will automatically install, build a profile of your hardware and software, and display this in your web browser.
For the Belarc log, save the file with an "html" extension. (example belarc.html)

This will help us trouble shoot the issue.

I sent a reply to the above explaining that this 100% CPU issue is not an issue with MY computer exclusively, but with a number of NOD32 v3 users so the problem lies in their software. Am I correct?

[Banger696]

I would think you are correct but it might be worth jumping through the hoops to get a diagnosis from Eset.

[twl845]

-{ Quote: "I would think you are correct but it might be worth jumping through the hoops to get a diagnosis from Eset." }-
Or I could jump through one hoop and go back to v2.7.:)

[Joliet Jake]

Damn, this has been happening to me these last couple of days.

XP Home
Comodo V3 firewall
NOD32 V3.0.563.0

Tried switching off all protection in NOD but that did nothing. I have to reboot to get it to calm down.

[twl845]

-{ Quote: "Or I could jump through one hoop and go back to v2.7.:)" }-
I sent an additional reply to Eset, saying how we had quite a few people at the forum who had the 100% so the problem must be in their software, and they replied saying they have a number of reports and I could go back to v2.7 or continue if I wish.

Just had ekrn.exe at 100% CPU again for the third time since installing v3.0. I'm not running any software firewall and there doesn't seem to be any pattern to it. The only way out when it happens seems to be to reboot.

[trjam]

I said this all through the beta. I could install the suite and it would work flawlessly. On reboot everything came to a crashing halt. Never could figure it out. I have 2- 2 user licences still active and would love to upgrade to the suite, but this is the reason I cant. Not that I dont wont to, I really like Eset, but I also think if you are using Vista this may be the issue and if so, Microsoft is the issue to.

[Zarra]

I had my first high ekrn.exe CPU usage last night on my Vista laptop and had to reboot to fix the problem. I had v3 installed on my computers since the day of release.

Same happening here (99% CPU usage on ekrn.exe)

And not using any of those third party products either.

[Nahaz]

If you have contacted ESET then I suggest you do send them the relevant logs they are asking for. It does help them to determine where and why things like this happen.

[Joliet Jake]

I've not had a repeat of this issue since the 28th.

[doodek]

no reason why its happening, only one way is killing process

[CrunchieBite]

Add me the the growing list of 99% CPU usage victims.

Eset Nod32 v3.0.566 Business rolled out to a number of clients using the same package and configuration. This morning, two client PCs decided that ekrn.exe needed some exercise and lit the CPU's up to 99%.

Neither machine is running any firewall other than the standard XP Pro SP-2 / Vista Business firewall and in both cases, the only option was to End Task the process. After the process was terminated, it automatically restarted with only 1 or 2% CPU usage.

Me thinks there is a bug in there somewhere! :-\

[pyr0rrzzz]

Same problem here, guys.

I just tried to open a video file but nothing happened. Checking my task manager I noticed the high CPU usage of ekrn.exe... This sucks.
I've upgraded to V3 a few days ago but didn't have any problems so far. Killing the process helped, though...
Btw. I'm using CFP 2.4, too

[The_Goon]

You can also add me to this, pc has been unresponsive, looked in proceses and ekrn.exe running at 99% cpu, went back to 2.7 since lunchtime and pc running fine. I also had Comodo new firewall and uninstalled that a couple of days ago went back to pc tools one after seeing this thread but pc was still unresponsive, but as i said gone back to 2.7 and now everything is ok, for now.

[Banger696]

-{ Quote: "I've not had a repeat of this issue since the 28th." }-

Me either since my re-install on the 27th but it seems lots of other people are getting it. I also haven't rebooted since then so who knows. :lurking:

[qwer1304]

Same thing here - ekrn.exe suddenly consumes 100% of CPU.

Configuration: Win32 XP Pro w/ latest patches.
NOD32 BE v3.0.566.0 latest virus DB

Restarting or killing the process helps for a while.

ZA firewall or no firewall at all have no effect.

Disabling NOD32 doesn't lower the CPU.

Examining the handles with PE doesn't reveal anything special.

Bummer :( :thumbd:

[Joliet Jake]

Noticed whenever I access the advanced settings eken.exe uses 100% CPU for around 8 seconds.

[jilo]

Hello,

I have the same problem with ekrn.exe at 99% >:( And I have Comodo 3 too.
I have put Eset products to signed safe list, but no change. Sometimes ekrn grows to 99% CPU, and I have to kill process two or three times to return to a normal usage.

I am wondering if the problem is not due to Web filter because it always comes when I am on the web with Firefox.

No problems here with erkern CPU usage using the Windows Firewall, CFP v3 or the new CFP V3 beta. I've ticked and unticked my web browsers, including Firefox and still haven't noticed anything.

[jilo]

It's true that everyone associates Comodo with this problem, but i dont know if it's linked ... maybe it's only an Eset problem...

Personaly I didn't have any problem with NOD32 3 and Comodo 3 at the beggining. Maybe an update is in cause... I will send an email to Eset hotline.

I am using OA with NOD32 3.0 and having no cpu issues. I know there are temp fixes for Comodo cpu using in there forums.

[enduser999]

Well I also seen this behavior today on a XP system that has Sunbelt Personal firewall so my original post that started this thread, seems to indicate that the problem is not related to firewalls. This time I was deleting 4 4mb files from a directory and the system, AMD3500_ w 2GB memory and XP Pro, just hung until the files were deleted. The NOD version is 3.0.621.0.

[piranha]

i resolved a similar problem, check this solution

[enduser999]

I noticed that fix. However I never see svchost hogging the CPU only ekrn.exe this time during deletion or restoration of 3 4MB+ files.

[enduser999]

Has there been any updates on this problem? My laptop was in a deadly embrace which lasted about 5+mins until I eventually was able to restart XP. Ekrn.exe was using 99% of the cpu all this time!

[Joliet Jake]

I went back to V2.7 until this and other issues are sorted. Perfection again!

Same here. At least I can still use my laptop while the unraring is underway. Too bad this problem is still persisting in ver 3.
