The upgrade from 6.0.13 went just fine :D and the mail server is working perfectly stable for more than a month now.
The only modification that I did was to update clamav to 0.97.3 after the first week of usage.
I have another problem which seems to be known in the 7.x versions of Zimbra: the server has high CPU usage by the java processes. It is stated that this bug is fixed in the patchset for the 7.1.3 version but some people are reporting the same problem even after applying the patchset to 7.1.3.
So I am waiting for an update patch... and the new port :rolleyes:
On 6.x there was one java process, and on 7.x there are two, which are terribly slow on "zmcontrol stop". Is this the same problem I just mentioned or there is a known setting for this?
