guam - high number of crashes

in my pretty fresh kolab (16.1) I have some trouble with a high number
of guam crashes and suspect the crashes to also destabilize cyrus.

I currently have 5 domains and 21 mailboxes in use, plan is to scale
higher. Because of the occuring guam/cyrus issues I stopped migrating
more users to the kolab system.

I have thousands of crash reports per day, syslog then shows:

Mar 10 12:02:26 mail guam[13456]: 12:02:26.753 [error] CRASH REPORT
Process <0.17627.1> with 0 neighbours exited with reason: bad argument
in call to
in eimap:joined/2 line 487

Logfiles in /var/log/guam show detailed CRASH and ERROR reports.

Additionally I'll receive the following syslog errors for several
existing mailboxes:

Mar 10 15:23:49 mail cyrus/imaps[2577]: IDLE: error sending message INIT
to idled for mailbox!user.alice: No such file or directory.
Falling back to polling every 60 seconds.

Testusers describe errors when accessing their mailboxes with
mailclients (e.g. Thunderbird), like mails aren't downloaded, after
sending mails can't be stored in sent folder.

Does anyone have a clue, what could be wrong or how I could fix my issues?

Thanks very much!
