I have a fresh install of Zimbra 8.0.2 on ubuntu 12.04.1
From this time i am wondering why my backup space i growing so much.

Now i have found the issue.
The file "/opt/zimbra/data/ldap/mdb/db/data.mdb" have a size from 80GB!
Code:
524K -rw------- 1 zimbra zimbra 80G Jän 21 09:20 /opt/zimbra/data/ldap/mdb/db/data.mdb
The strange thing is my data partition is only 50GB !

Code:
/dev/xvda3       50G    4,2G   44G    9% /opt/zimbra
I have done a filesystemcheck and there are no problems.

How does this work and how can i fix them ?
