  • Applies to:
  • Virtuozzo containers for Windows

Symptoms

  1. The hardware node experiences BSOD, pointing to vzcore.sys driver.

    Memory dump analysis produces the following (or similar) call stack :

    Child-SP          RetAddr           Call Site
    fffff880`88aa05c0 fffff800`01c4126d nt!ExfReleasePushLock+0x62
    fffff880`88aa05f0 fffff880`0c7095d5 nt! ?? ::NNGAKEGL::`string'+0x56aea
    fffff880`88aa07e0 fffff800`005fd000 vzcore!MyCmLoadKey+0x555
    fffff880`88aa0920 fffff880`88aa0950 0xfffff800`005fd000
    fffff880`88aa0928 00000000`00000000 0xfffff880`88aa0950
    
  2. (Or) The hardware node hangs completely on a mass container start-up event.

Cause

The issue can be caused by Windows Defender service running inside the container. It produces great load on the registry.

It is highly not recommended to use any Antivirus solution inside containers. A hardware node should have its own Antivirus, which provides protection for containers as well.

Resolution

Check if Windows Defender service is running inside the containers and disable it.

The following command will stop and disable Windows Defender in all running containers :

for /f %i in ('vzlist -Ho ctid') do vzctl exec %i sc stop windefend && vzctl exec %i sc config windefend start= disabled
