After moving to a new Server (Ubuntu 6.06 32 -> 10.04 64), the logger service is not working correctly. In the Admin GUI Server status shows:
Server status data is not available. To see the server status, loggers service must be installed.
Running zmcontrol -status shows everything is working correctly. The mail server has been functioning without any problems, except for the stats and status not working.

I suspected this may have something to do with the self signed cert we had to create during the move(in hindsight I think it might have complained of something in the process). So I decided to recreate the cert, and noticed that I am getting two errors.

On step 3 from Administration Console and CLI Certificate Tools - Zimbra :: Wiki, I get the following:

And on step 4:

unable to load certificate

I have moved mailboxd/etc/keystore out of the way and tried this, with the same results.

So far I have been unable to locate an existing solution in the forums.
