I have a Proliant DL580 G2 that keeps going into ASR shutdowns. I've dealt with Microsoft Premier Support and they state it's not their issue as I can't get the server to generate a memory dump when it locks up. As per their line of reasoning, the issue is hardware-related. The SmartStart diagnostics reveal no issues on any hardware in the server, and I ran the full test. All drivers/firmware are current as well. In the process of attempting to fix this issue, I've replaced everything in the server save for the SCSI backplane, array controller and the power supplies. The server's temperature is stable and not elevated at this point, nor is it anywhere close to being elevated. Additionally, the WMI Performance Adapter service, which is stopped and the startup type is set to manual, keeps stopping and restarting. The server in question is a DR box; the production server has identical hardware to the problem box but doesn't exhibit the same problems. Both servers have VMWare GSX installed on them and run two VMWare guest server sessions apiece. I'm also looking into what could be causing the WMI Performance Adapter service to keep stopping and starting, but the production (working) server has the same symptoms but it doesn't lock up. Last, I've updated the symevent.sys file as the server has Symantec Antivirus installed. If anyone could offer some insight as to what I could try next, I'd appreciate it.
