Exchange 2003 - ESE event ID 510
Posted on 2010-09-06
My exchange 2003 sp2 server running on SBS 2003 SP2. Has hit the maximum size limit of 75GB, actual size is 77GB.
I deleted lots of email from 2 of our larger mailboxes, this brought the size down to 68GB. After running the cleanup agent to free up the space on the database. I get a message in the event log confirm the online defrag has finished and 10gb of space was removed from the database.
Shortly after this completed I start getting ESE event ID 510 every 5 to 10minutes and performance on the server is extremely slow for anyone using exchange.
In order to fix the slowness and stop the 510 errors I need to reboot the server. What's strange is after a reboot the server show that the database is back to 77GB and it will run fine for a day. Then the online defrag runs automatically and reports the 10gb has been removed, then the 510 erros come back it starts all over again. I've rebooted the server for the last 4 days.
I assume my only option is an offline defrag, but that will require the server to be down for too long. Also, there are no disk errors or any other hardware related problems that I can see. I was able to run a full NT backup on the database so I don't think it's corrupted.
Anybody have any ideas that don't requirre takitg the server offline for 2 days?
