Hi, I am having issues with a 2003 Server running ESET Endpoint AntiVirus v5.0.2126.0 After approximately 10-11 days said server runs out of Non-Paged Pool memory and becomes unstable requiring a reboot. In the attached images, I have shown the NPP usage reported by Process Explorer; The tags in PoolMon showing that "None" has approx 100MB usage. And Dependency Walker showing the EAMON.SYS having a call to ExAllocatePool. EAMON.SYS is the only driver residing in memory that has this call and hence making me suspect it is the cause of the high "None" tag usage. Has there been any other reports of such an issue? Is this known (or wrong)? Is there a workaround/patch available? Any assistance would be much appreciated.
