Disk space

[Stew Schneider]

/ is full. Trying to trace it down, it seems that /var is the big user 
(to no one's surprise). I observe:

root at stewart:/var# du -cks *|sort -rn|head -11
11408588        total
11168632        cache
207648  lib
9180    tmp
7244    log
7100    crash
6684    backups
1600    spool
308     run
168     www
8       ax25

11 gig of cache seems an awful lot. Can any of that be dispensed with?
