I'm getting this error when attempting to visit the Admin interface on my OTRS Jumpbox:
The proxy server received an invalid response from an upstream server.
I can't use that interface to do anything unless I go into the VMWare Console and restart the server there.
While auditing our backups today, I noticed that we had a whole bunch of tmp.* folders and a bunch of .tgz files of 0K or 1K size. The tmp folders had largish files in them (several hundred megabytes).
Since this didn't look right, I rebooted the server from the VMWare console, and started a backup. The backup failed to complete and hung the server.
I've also been getting these errors (via email) every day at the time the backup should be finishing:
DBI connect('database=otrs;host=localhost;','otrs',...) failed: Can't connect to local

Please help me. I need this server to backup properly.
