Services shutdown for no reason 1

[EverquestAddict]

Greetings,

Sometimes, maybe once every week and a half, the Exchange services go down for no apperant reason. There is nothing in the event viewer as to why it happened. I'm guessing Norton for Exchange. But if I disable it, that will open us up for viruses. Kind of a catch 22. The only other thing I see running at the time of the crash in some "online defragmentation" thing. Don't know what it is.

Anyone else had similar problems?

I'm having a similar problem. About once a week, usually the weekend, we are unable to receive/send external email. Internally, works fine. The only solution is to reboot our firewall and than everything works fine. Any ideas?

Thank God!!! I thought it was just me. We do have a Sonicwall Firewall though. But I haven't seen anything on the firewall's logs to indicate a problem.

I wonder if anyone else is having the same problem?

One thing you may want to do is check your application event logs for 1221 events, these indicate that a full pass of Online maintenance / OLD(on a DB has been completed by Exchange.

If you are not seeing these it may be worth altering your maintenance window i.e make it bigger to ensure that this is completing (note a window too big will lead the process to start again). One thing that I would like to make clear is that OLM/ OLD will continue where it left off from it may take several passes of the DB before a 1221 event is logged.

If you are updating AV software and it coincides with OLM try changing it or even disabling it for a short time. Its also worth staggering backups and OLM so they don't conflict too much.

AH HA!! That what I was wondering. The Backupexec starts at about 11:00pm and the online defrag starts at 1:00am. The Backupexec is still running by this time. If that online defrag is running when users start to logon in the morning, will that stop it or corrupt it?

I have the Norton AV updating at 8:00pm. But I will fine tune the above operations for a smoother night. Thanks!!

I too have my this problem on my server. I do not run Norton for Exchange (I run NAV for the server only). My services stop periodically ( just like you mentioned) I notice it then restart them. I have caught this during the middle of the day. So this makes me think it may not be related to the defrag operation. I figure its an undocumented M/S feature (to rest the smtp service).

What times are your online defrag running? I think the default is 1am to 5am. Check to see if your Norton AV is scanning the databases. Norton for Exchange seems to scan the mailboxes fine, but Norton installed locally has problems sometimes scanning active databases.

you have to configure norton to exclude specific exchange directories or else possible corruption may result.
