BackupExec Hangs/Crashes Domino Server

Hello folks...

I'm running Domino 6.5 on Win2K Server. It's been running great for months.

I recently installed Veritas BackupExec for Windows Server 9.1. I also installed the Agent for Lotus Domino Databases in order to do online backups of Domino.

What I am experiencing is that during the backup, the backup job seems to hang and then eventually fail. The Domino server is still responding at first, but then when the backup job finally fails, the Domino server seems to fail as well.
The failure is occuring at different points - ie. it's not always the same database. The total size of all the Domino dbs is 40GB. Last night it got 98% of the way done, and then stopped. The job was still active, but all network activity stopped, and the byte count stopped incrementing. On the Domino server, the beremote.exe showed 0% CPU (it was higher when the backup was running). Eventually the backup job failed, but it waited several hours before doing that.

One initial problem I had was a memory leak that caused the domino services (nserver, nupdate, nhttp, etc) to grow and grow until the server stopped responding. The backup seemed to make this problem worse, but I believe I've fixed that by adding two lines to the notes.ini on the server: ContrainedSHM=1 and ConstrainedSHMSizeMB=550. This restricts the Domino server workspace to 550MB of RAM (the server has 1GB).
For reference on these issues see here:
http://www-10.lotus.com/ldd/nd6forum.nsf/55c38d716d632d9b8525689b005ba1c0/1db73bb3d91c918c45256ced003a99b7?OpenDocument
http://www-1.ibm.com/support/docview.wss?uid=swg21095911

So now the Domino server isn't spontaneously hanging during a backup due to memory problems, but the backup jobs are still failing for seemingly other reasons.

The Veritas error being created is this:
Completed status: Failed
Final error: 0xa000fe30 - A communications failure has occurred.
Final error category: Server Errors

I've searched the Veritas site and found some seemingly-related articles, but nothing has fixed this yet.

Any ideas or solutions would be great.

Thanks...but I'm not sure I understand what that registry key is actually doing...

Enable Offline Backup = 1

To me 'offline backup' makes me think that the Domino server is shutdown. What I want to do is backup the databases while the Domino server is running. Do you remember what the problem was that you were having?

Not sure if Domino requires it or not, but on our SQL server boxes we run Open File Manager.  Possibly the issue could be related to the backup trying to access a database that is in use by another process?  Thereby causing it to fail?

Three Reasons Why Backup is Strategic

Backup is strategic to your business because your data is strategic to your business. Without backup, your business will fail. This white paper explains why it is vital for you to design and immediately execute a backup strategy to protect 100 percent of your data.

thanks aszumilo, but no...at least it's not *supposed* to need that from what I've read. The Domino agent should be all I need. I do have a copy of the Open File Agent, so maybe I'll test it out.

Update:
The actual backup seems to be completing now...all I did was reboot the Veritas server. <sheesh>

Anyway, Domino is still hanging after every backup...the nserver.exe CPU% goes up to around 30% and stays there after the backup finishes. Shortly later (within 3 hrs) everyone starts getting 'server is not responding' messages and I have to reboot.

I've opened up a case with Lotus on this, so we'll see what happens.

I opened cases with Lotus and Veritas, but never got things working properly...anyway, it's not relevant now, because the email configuration has been changed. Thanks for the help.
