PSOD Issue on vSphere 5.1


We had an issue about after upgrade vSphere 5.0 to 5.1
Somehow, when loaded or not loaded 5.1 nodes goes down , this is not only about upgrade, fresh installs have same issue
We fixed the issue with vmware with execute such command on console  “esxcli system settings advanced set -o /BufferCache/MinZeroCopyBufferLength -i 512” . This command need a restart of node
After long tests we saw that there is no issue with it  and vmware inform that with ESXi 5.1 Patch 01 problem will be solved.

You can find out what i got an errors
Also vmware inform that this is not hardware issue looks like software issue

  2. Pls apply the fix, it will be solved

      Can you tell me your VM support case number? I have exactly the same issue and have a support ticket open with VMWare. If I can reference your case, it will probably expedite the resolution of mine.
      Did they say anything about publishing a KB on this? Lots of other seem to have this issue –

      • My SR number is ‘12228564210’
        No KB, but i write down my blog next update looks like they will fix it, a workaround which applied to me okay until now
        I never seen such link but this fix help me a lot
        Did you try it ?

  3. This fixed it for me too before VMware got back to me. They also strongly recommended installing patch
