I think tere is a need for fsck on this partition.
/var is used by many daemons for logging, mailqueue etc., so maybe the first 
thing to do would be to stop as many daemons as possible and leaving only ssh 
to get to this system remotely?
I really don't know how much dangerous could be unmounting /var on a live 
system in such case.
