Since this morning something weird has been going on. We're running Kerio Connect 7.0.0 build 1067 with ~30 active users on a dual-CPU dual-Core Xeon server with 4GB of memory and SuSE Linux. I was unable to connect to Kerio this morning via Thunderbird, so I started digging around. The webinterface login window loads, but I cannot login (Firefox hangs at connecting to...). Kerioadmin loads just fine and works. However, I found the process mailserver caused between 100 and 200% CPU load. Not being sure what had happened and with 30 users in my back asking why they cannot access their mails I simply restarted the Kerio Mailserver via the init skript in /etc/init.d and everything worked just fine.

About three minutes later we were back to zero - login impossible, Thunderbird unable to connect and the mailserver process at ~160% cpu load again. Third time's a charm, so I restarted Kerio-Connect again. And again after three or four minutes of running just fine it was unresponsive again. According to kerioadmin there were dozens of active connections, ten alone by my own smartphone. Except for that I did not see anything unusual. About ten active webmail sessions, a few HTTPS/ActiveSync sessions, a few IMAPS and IMAP sessions.

Any idea what could be going on here? This server has been running fine four a few months now, and we haven't changed anything in terms of hardware or software, except for ten new users that we added last week.

Update: apparantly it's my HTC Hero that causes this behavior. I've tried it three times now - as soon as I reenable my phone's wifi connection and it connects to Kerio Connect via Exchange ActiveSync the mailserver crashes. I've deleted the account an created a new one with the same result - as soon as it connects Kerio crashes.
