For about the last month, our web mail service will hang 12-15 times a day, each time for about 5-7 minutes. It seems to happen more often during busier times, but our service indicator (monitors _index page) has shown it down in the middle of the night. So far, it is only the web mail as IMAP and SMTP are not seemingly affected. I have loaded up squirrel mail as an alternate web service and will see if connecting to IMAP with all of our users causes the same problem as with the internal web mail. I was wondering if anyone had ideas on what to try.

All help is appreciated, thanks
