I'm a little stuck with this one, so I was wondering if anyone else had seen anything similar.
On a customer's Scalix 11.3 (running on SLES 9) server, we've started getting reports of SWA users not seeing new mail until they log out and back in. This issue has only been reported in the last 2 or 3 weeks. Also, sending mail is affected in the same way. Restarting scalix-tomcat fixes the issue for a while, but it soon returns.
There are some NPE's logged in scalix-swa.log that I believe relate to this issue:

... skipping the last 18 lines as irrelevant...
This strikes me as a possible IMAP issue, however the IMAP service doesn't appear to be having any issues, and the problem persists over scalix restarts. I've also run an in-depth scan on the mailstore (omscan -aAvfxe).
If anyone has any ideas, I'd be most grateful!
Cheers
