Yeh yeh its legacy i know but its still in production.
heres the specs;
- farm of around 30 guests
- 5 vsphere servers in vcenter
- emc iscsi san with 24 spindles
- Server in question is 32bit 2003 server. memory is around 3.4gb used of 4gb available CPU is 2 sockets with 4 cores per socket. It was P2V'd a number of years ago
- all other server appear to be fine and don't have any performance issues.
I have an issue where the 2003 server is hanging and becoming unresponsive. End users who use the software and website that talks to the SQL database are complaining of poor performance also. the UI desktop pauses and hangs at the same time
I have checked the performance of the host vsphere server that runs this guest and resources are not overloaded. CPU maximums are around 40%
I have loaded perfmon on the guest and added av/disk queue counters, cpu % and memory/page file. When the UI hangs, users experience performance issues the av/disk queue hits 100%. disk queue returns to normal and performance responsiveness returns.
I have also run perfmon on another server that resides in the same datastore and vsphere server and i don't see any of the issues/hangs or disk queue maximums so it would appear to be guest related.
Does anyone have any suggestions?
