Rule: 1002 fired (level 7) -> "Unknown problem somewhere in the system."
Portion of the log(s):

any ideas?

permissions problem somewhere? Or is /var running out of space?

permissions where though? /var is not a different partition, and / has lots of space left (100GB or so) could it be that the users quota is running out?
