Thanks for the reply. You are saying exactly what I said/read and felt. We did go through IBM and Notes support and they couldn't come up with anything tangible to explain the hangs.
People were constantly complaining about the slow-downs/hangs. When we tracked them for a while, we noticed they always occured during the archlog dumps being performed, every 2-hours. I think IBM was the one who suggested the MOUNTWAIT parm (the Domino person handled this). I told them that none of the management classes go straight to tape. *ALL* backups (logs, daily, weekly) go to disk, first, and this parm shouldn't make any difference. When we added the MOUNTWAIT=NO, the complaints stopped and our monitoring showed no more "seizures". I too realize it doesn't make sense but it did make a noticible difference.

If what you say is correct... and all log backups are going to disk and not tape, using the "/MOUNTWAIT=NO" parameter should have absolutely no effect. I have a feeling that the "accident and experimentation" are probably more of a "coincidence"... but you never know. I would recommend placing a call with the IBM Support Team so they can help you can get this sorted out.
