"The server was unable to allocate from the system nonpaged pool because the pool was empty."
We have a server which decides, about every 2 weeks, to throw this error every minute to the second in the Event Viewer. At about the same time, the server starts to do weird things, including acting very, very slow, refusing inbound IIS and RPC requests and many other things. To me it reads as though it is some sort of (Virtual) Memory issue, but I'm not too sure.
Every time a restart of the server is required, which isn't really acceptable seeing as this can happen at any time of day or night, and not necessarily when the technicians are on site to resolve the issue.
The server was upgraded from Windows 2000 using an in-place upgrade (not my decision) and was migrated to new hardware at the same time. We have several other servers running on exactly the same hardware (installed at the same time) without any issues; it's just this one which causes the problem.
Windows Server 2003 SP2, fully patched. High power server - Dual Quad Core CPUs, 4GB RAM and almost a TB of disk space, although that wouldn't - shouldn't - affect it. :-)
Does anybody know what causes this, and have a possible solution we can implement?
