We have two Windows 2003 x64 R2 Enterprise servers in a file server cluster.
They're both running on HP DL360G6 servers that are about 3 months old and
are accessing an EMC CX700 array with QLogic fiber cards. The servers are up
to date with the Windows patches and the various HP drivers.
Over the last few months, we've been seeing some of the "2021" event log
warnings from the "SRV" with the message "the server was unable to allocate a
work item 1 times in the last 60 seconds". Occasionally, it's "...2
times...", but I've not seen anything higher than that. They've been fairly
frequent, but we've not noticed any performance issues.
However, the last week or so we've been getting reports that the server is
"slow". We checked the logs, and we're seeing a lot more of those warnings
(pretty much every minute).
Over this last weekend we did a failover to the other node. We're still
seeing the warnings, but it looks like the performance is back up.
I've done some searching on the net, and found some info about adjusting the
registry settings regarding memory, but the information I've found seems to
be for the 32 bit versions of Windows, not x64. Since I know the 64 bit
version handles the memory differently, I'm hesitent to apply settings for
the 32 bit memory managment system.
Any suggestions would be appreciated.
