" VAR space running out and incapacitating the whole device"

Hi John,

in most cases old maintenance files, UCS archives, qkviews and tcpdumps are using up space in /var.

To locate the 10 largest files on the system, issue the following command:

find /var -xdev -type f -exec du {} \; | sort -rn | head -10

And there is a whole KB article that will help you sort this issue:

K14403: Maintaining disk space on the BIG-IP system

Best of luck
