Kolab 3.4 - Apache mem usage and mysql db grow

[Tobias Brunner]

Hi,

> host is used.

I see a similar problem, Apache2 needs to be restarted every day to free up 
memory and stopping it from eating all CPU power...

> 2. Mysql database is growing very fast. File ibdata1 is 245Gb now.

Same here, the database has grown really fast!

Any ideas what could be wrong?

Cheers,
Tobias

PS: I'm running Kolab on Debian 7.8 and Ubuntu 14.04 LTS, same behaviour on 
both OS.
