ESE Event ID 733

Question

I was doing some routine maintenance on our Exchange servers yesterday. After a server reboot I went to the event logs to review for any issues. I noticed several event id 733 Source ESE for only 12/11 -12/12.

Information Store - DatabaseX (19368,R,0,15.01.2375.017) DatabaseX: Online Maintenance Database Checksumming background task is not finishing on time for database 'C:\DatabaseX.edb'. This pass started on 11/2/2019 and has been running for 66677085 seconds (over 771 days) so far.

These events are only on the active node of our DAG. I have a couple of these events for each database and they only span 12/11 - 12/12.

Using this article I searched for the event ID's 735,736,737. I found event ID 736 which is database maintenance is starting. I had many of these events going back as far as the log truncation point.

Is this something I need to be concerned about? Defragmenting for over 700 days seems alarming. Any insight would be appreciated.

Thanks-

Answer 1

I wouldnt bother honestly. That requires taking the database offline or running against a passive copy, I dont think there is much value there.
With the reboot you may have popped something and I would just keep any eye on it.

Answer 2

Could be some resource constraint. I have seen some who claim adding more memory , but I wonder if something is just stuck.
Activating the databases on another server may do the trick.

Answer 3

Do you have any anti virus or backups running?

Answer 4

We have antivirus running on this server but it excludes all of the Exchange program files, database and log directories. No backups are done from this server.

Answer 5

I activated the DB's on different servers last night while doing maintenance. I am not sure if that is what caused the alerts or if it was the reboot. would it be worth checking do see how fragmented the DB's are? I think I can check that with ESEUtil.
