We've implemented a new core server based on Windows Server 2008 64-bit and LANDesk Management Suite 9.0.
The core server is a virtual machine with 4 dedicated CPU's.'
We've experienced a huge performance impact on the core server a few times this week. Alle CPU's are working on 100%. This shouldn't be a problem. Unfortunately, remote control isn't possible when this occurs. Our helpdesk uses remote control to control clients and get asked for credentials when they try to. We think this is due to a problem on the core server in resolving group membership in Active Directory for the helpdesk users. When the performance hit on the CPU's is over, remote control is possible again.
We've tried to analyze what is going on on the core. As far as we can see, the Custom Job Processor (Custjob.exe) and some ISS Application Pool Processes are the cause for this performance impact. We need to figure out how to solve this issue.
What does the Custom Job Processor do? How can we find out what it is that this process is doing at the time of the performance impact?
Thanks in advance.
