BSOD with LnS 2.07 on Win7 x64

I've been getting more and more of these. Once per week.

lnsfw1.sys
The driver is attempting to access memory after it has been freed.
STOP: 0x000000D5

OR

lnsfw1.sys
STOP: 0x000000C4


My LnS Settings (LnS 2.07 x64):

- Phant0m v8-003-04
- SPI : OFF
- Raw Log : OFF
- Anti-flood: OFF
- Plugins: ARP, EditRawRule & PluginLookAtThisIP (latest versions)

I don't think anything special has changed on my setup. Clearly not my hardware or the LnS settings. Heats are well within control. When crashing the system has not been pressed hard.

The only one I know that has changes are the system updates (via Windows Update).

I have also re-installed the LnS drive in case it has been corrupted.

Any ideas?

 

lnsfw1.sys being Application filtering driver.

Having the actual minidump file sent would be more helpful when troubleshooting.

At least one of the problems can be linked to the activated Deadlock Detection in Driver Verifier, not activated by default Windows install.

1) Click Start, click Run, and then type verifier.

2) After Driver Verifier Manager starts, click Display Existing Settings, and then confirm that Deadlock Detection is turned on.




3) Click Back.


4) Click Create Custom Settings, and then click Next.


5) Click Select Individual settings from a full list, and then click Next.


6) Click the settings that you want to turn on, make sure the Deadlock Detection check box is not selected, and then click Next.


7) Click the drivers that you want to verify, and then click Next or Finish if you choose all drivers on your computer.


8) Restart the computer.





after the above I would recommend running System File Checker to scan for and replace possible corrupted files, .. run Command Prompt with Administrator privileges and type sfc /scannow

 

Thanks. Minidump:

Deadlock Detect has not been on and I did not turn it on:

Should I turn it ON (it is OFF and has been OFF, afaik)?

I'm now running with LNS completely uninstalled and using the Windows Default firewall (I'm behind NAT and hw firewall on a known clean system) to see if issues persist.

 

Issues won’t persist because it was linked to Driver Verifier complaining about a bad condition with Look ‘n’ Stop - Application filtering driver (lnsfw1.sys). By default none of those tests are enabled on the Look ‘n’ Stop driver, so I would disable the Driver Verifier checks on lnsfw1.sys and things may run without the Driver Verifier stop errors.


btw, I've enabled those three tests on lnsfw1.sys and restarted, I'm going to see if I can reproduce the BSOD on my system with Look 'n' Stop 2.07 running on Win7 x64 and report back.

 

Have you done Windows Memory Diagnostics?

Start \ Run or Start \ All Programs \ Accessories \ Run
And enter in mdsched and click OK button

 

The minidump you attached was for STOP: 0x000000C4, if you have one for STOP: 0x000000D5, it would be nice to see it.

Also, if you haven’t already, I would e-mail Frederic and point him to this topic.

 

sorry for dealy, have been occupied.

First, thanks for all the help.

Ran MS mem diag, no probs. Will run also memtest+ overnight next.

Unfortunately rest of the minidumps are now gone. Have to wait for a new BSOD. Shouldn't be more than a week

 

Tomorrow will be a week for me running the driver verifier on lnsfw1.sys for both Windows 7 systems.

The x64 lnsfw1.sys I’m with is I think a unofficially released version, but for Windows 7 x86 system, is simply running the latest official version.

x64 Windows is running on a Desktop PC, x86 running on my NetBook
