I just performed the upgrade the Zimbra 5.0.11 from Zimbra 5.0.10 and the actual upgrade went as expected, no different from the previous upgrade.
When I came in the next morning however, the load on the box was over 10 and Zimbra was acting incredibly sluggish, and in some cases just plain timing out. Before the upgrade, the load on the box never went above 1.
I had to stop the logger by running /opt/zimbra/bin/zmloggerctl stop to make the box useable. Once I stopped zmlogger, the load drops to well under 1 and is functioning as normal.
I am in the process of converting my entire company from Exchange to Zimbra, this is just terrible timing. Can anyone shed some light on why zmlogger is dominating the box after the upgrade?
Thanks in advance for any help you might be able to give!! It is certainly appreciated.
