MSDE Throttling

Unity 4.05, Voicemail Only, MSDE & Exchange on the same box. approximately 200-210 subscribers. When they try to send a message to all subscribers, unity locks up. Looking through the event viewer, the only errors I see are a lot of MS SQL errors complaining about the server being "optimized" for 8 users & requests exceeded it by X -- those messages continue with X growing.

I have never seen this error before, but then I haven't had anyone want to send messages on a regular basis to all subscribers or other large distribution lists.

Has anyone seen this before? Is the fix to upgrade them from MSDE to SQL 2000?

I was just told you can throttle the MWI activity for a DL via the Bulk DL Management tool - that might be something to try.

Re: MSDE Throttling

John, in general you are correct - upgrading to SQL 2000 would remove the workload governor and you wouldn't see that error anymore.

I can only speculate, but since this only kicks in when there are 8 *concurrent* workloads, it seems like sending a message to the DL isn't the cause itself, especially since Exchange does the message delivery. Rather it may be something downstream - message notification/delivery on multiple ports perhaps. Is there anything unique about the way message delivery is setup on the system?

Excellent Suggestion! That did the trick, it's now working fine.

Re: MSDE Throttling

that seems reasonable. I didn't think about MWI notification doing it. i wasn't able to see what it was doing during the error -- i only got the call after it locked up & just looked at the event logs. There's nothing unusual about the setup as far as i know -- other than the fact that they are nuts about distribution lists ;)
