[Lumiera] unscheduled Server maintenance

[Christian Thaeter]

We had our harddisks FULL, thus I stopped all servers immediately to
investigate the cause. Stopping the Servers already freed a lot memory,
Possibly some long running processes kept file handles open for already
deleted files. Please everyone who is responsible for one of the
vservers check your configs and monitor your server for the next days.
Anyone did some noteworthy change? 

I've listed all files on all servers now, sort by size and don't see
anything fishy.

I am working on restarting the servers one by one now.
