SWA lockup during startup after login

[kea13]

Hi,

we have a Hosted Edition in version 11.4.3 and are experiencing a rather strange behavior with a number of clients:
After successfully logging in SWA loads up and hangs during "Loading Mailbox data". We do see the SWA- and IMAP-processes for that particular user. Closing the browser and re-connecting doesn't help as SWA will go through the startup up to "Loading Mailbx data" and hang again.
To avoid loss of data we then go ahead and "sxmboxexp ... --force", "omdelu" (after killing off the processes), recreate the user in SAC and "sxmboximp" to restore the data.
While this is majorly cumbersome, it does help .... for a while: then all users start to experience the abovementioned problem, and this time all we can do is reboot the scalix server (on a hosted edition this could very well be seen as a showstopper)
Oh, and there's neither an indication in the logs nor a performance- or connection-problem.

Any hints, tips, RTFMs? Please??
Cheers,
Roman

Roman, did you happen to solve this issue?

It seems like this only happens with users that have a lot of data.

Scalix version: 11.4.4
The outlook connector works like a charm
The IMAP cache of the relevant user has been cleared
omcheck -i -s shows no problems
omcheck -s -d shows no problems
Reconfiguring Scalix using the installer didn't help
Even a reboot was done

Is there any specific log file that might shed some light over this mystery?

The next likely step is to enable imap logging for the user and see whats going on.

There is a script which does this here.....http://www.scalix.com/wiki/index.php?title=Diagnostics

Thanks Les!

The thing is, that activating the IMAP logging involves the SWA interface for the specific user. Since there's no way to complete the log-in - there's no way to set the logging.

catalina.out looks ok. Nothing special there.

The only thing that resembles an error message is the following repeating message in the 'IMAP daemon' log in the SAC:

Code: Select all

REPORT IMAP Server Da(IMAP Server Pr) 07.07.09 10:12:56
[OM 24070] Debug message for Lab use :
imapSatelliteCommand: Satellite has died, tidying up...
User Name: DDD RRR / TTT/CN=DDD RRR

A quick search shows that this is probably nothing.

omtidyallu -M (to be on the safe side) didn't bring any love.

I'm an inch away from removing the user, recreating it, and just re-sync it with Outlook. It will solve it for the meanwhile, and leave the problem unsolved.

Any idea?

i dont get what you mean there.

Going by the original poster.....

After successfully logging in SWA loads up and hangs during "Loading Mailbox data". We do see the SWA- and IMAP-processes for that particular user. Closing the browser and re-connecting doesn't help as SWA will go through the startup up to "Loading Mailbx data" and hang again.

Is that what happens to you also? If so you've already logged in therefore imap is in play and logging will shed some light. If you have swa hanging before you even enter username and password then its a different issue and possibly not imap related and should be a different post.

It cant hurt to turn logging on and see what happens using the script from the wiki and runinng it from the command line.

enable_imap_logging -u "User Name"

Then look at /var/opt/scalix/??/s/tmp/imap.%u.%p (according to the script) as you try to login.

Les, you might not believe it. I know I don't...

It appears, that the reason was an old theme. That's all.

Every user that used this theme, got stuck right after the SWA popped up (login was successful).

And even weirder: even when creating a theme with the official samples from Scalix, with no changes, it still won't work. But that's an issue for another post...

Thank you for your help!
