SVCHOST ISSUE - 2008R2 XenApp 6
one of the SVChost.exe will randomlly appear and take 50% of the processor. (Server has two processor, so basically it is maxing out one processor) this process makes the server super slow, and eventally it will lock up the server. There are not event logs, or crash information - the server will eventally just lock completely up and we have to power it off - again nothing in the event logs.
It seems to happen more often when someone connects via RDP - but it is not everytime. And it was happened with no RDP sessions. The only fix is the power off and back on then prey it does not happen again.
If you kill the process, you immedaitly lose RDP and Citrix connections, and you cannot connect to the box or login. Existing connections stop as well.
Are first server was doing this, so we completely rebuild from scrath and still have the issue.
We have applied all of the updates based on this site, including hotfix 40. We are not running SP1 for windows.
We have an open case with citrix support, and they are saying they have never seen the problem. We have even started over, rebuilding a whole new system, and still we are seeing this. Anyone else with this issue??
The next time it happens we plan to capture what exe svchost.exe is using so we know with the problem. We basically are just sitting back waiting for the problem in our production enviroment.
Very surprised citrix support has not seen this - am I the only one out there? I know that hotfix 30 addresses something regarding svchost with terminal server (but we are not getting an event log error that matches that hotfix, plus we have hotfix 40 installed which includes hotfix 30)
