Hello Srv2003,

I already had some PSODs with (essentially) some white box (ESXi) servers that I use in a personal lab.

The first think I need to ask is if that server was upgraded or had some kind changed it’s configuration lately. If so, what changed?

Unfortunately, the information you provide is too little to be able to help you with a consistent answer.
Even so, I can point you two directions to VMWare Knowledge Base.
The first <a href=”http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006802″><b>Understanding an “Oops” purple diagnostic screen</b></a>, and this is the second <a href=”http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004250″><b>Interpreting an ESX host purple diagnostic screen</b></a>.

With all the trace you will be able to decipher it with the steps provided.

Please let us know about your steps and findings.

    hello, thank you for your reply. actually, that's pretty much all the information I have, but i can tell you that these ESX haven't been updated in a long time, just all of the sudden started to show the PSOD. also, I have a ticket opened with IBM, but from their side, apparently, this is not a hardware failure, still waiting reply from VMware, but basically, what they told me, even before having a look at the system logs, to make an upgrade on these ESX to 4.1
