I'd be interested in seeing your squid.conf file. I too, expect your cache is dirty. Again, attaching an strace session to squid might illustrate exactly why it's dying. Also, how does the "-C" parameter affect squid? Tim Rainier Information Services, Kalsec, INC trainier@xxxxxxxxxx "John R.

Allowed squid -z to rebuild and it will still die with in hours. Removed deleted all cache files and directories. I'll do that too and see what happens. > Why it dies while rebuilding storage. > Your cache is also looking dirty. > Can you delete all file and start caching again? > -----Original Message----- > From: John R.
