Currently I have a SQL server cluster running on a Windows 2003 Server that failsover every time the maintenance jobs run. The maintenance jobs include a Forced Reindex, Rebuild Indexes, and Defrag the indexs. The first two index jobs run in the morning around 6 am, and we fail not long after the job starts. The last index job runs in the evening around 6pm, and we fail about half way through. The server reports an error of 2019, which is that the system has run out of nonpaged pool memory. Microsoft has given us hotfix after hotfix to try and resolve the issue. Nothing seems to help. The hardware is not reporting any errors. It is Active/Passive setup with a fiber channels to the SAN. SQL server is setup on a RAID 10 configuration. THe indexs, tempdb, and backups are all on seperate RAID 1 configured drives. Now the this failure began after a the change to the configuration above was done. Before that we had everything on the RAID 10 drives. Any Ideas?
