/var/log is getting full

From the fix common problems plugin:
 

/var/log is getting full (currently 80 % used)

Either your server has an extremely long uptime, or your syslog could be potentially being spammed with error messages. A reboot of your server will at least temporarily solve this problem, but ideally you should seek assistance in the forums and post your

Any assistance in understanding what the problem is would be greatly appreciated.

Take your server out of the router's DMZ or don't forward the SSH ports to it
