More info:
I decided to restart squid and it refused. At that point it appears
that the redirector process ran away and the load went through the
roof. I ended up having to take it down hard. After restarting, the
box I found this in cache.log
2007/02/06 14:14:20| /var/spool/squid/10: (2) No such file or directory
FATAL: Failed to verify one of the swap directories, Check cache.log
for details. Run 'squid -z' to create swap directories
if needed, or if running Squid for the first time.
Squid Cache (Version 2.6.STABLE5): Terminated abnormally.
CPU Usage: 0.240 seconds = 0.156 user + 0.084 sys
Maximum Resident Size: 0 KB
Page faults with physical i/o: 1
So.... I ran the proscribed switch which I figure cost me two months
worth of cache, and squid went back to running just fine.
Any ideas as to what happened so that I might avoid it in the future?
Thanks

Hi all,
I have been working on this problem now for a day or so. I'm running
2.6.STABLE5. Towards the end of last week various pages begin to be
slow resolving and often required several F5's to finally load. The
problem changed over the weekend to pages not resolving at all but
being redirected to the search provided by the external dns servers we
use (opendns). Bypassing squid and connecting directly to the
Internet, using the same dns servers clears the problem up. Dig shows
that the zone files in the dns servers are correct for the urls having
problems. This would seem to eliminate the dns servers as the issue. I
think.
The cache.log shows no unusual entries. Access.log shows the url's
being requested.
The only thing that appears different as far as I can see is the
rcode section of the Internal DNS page of cachemanager. Here it is:

Before this issue came up, I never remember seeing anything beyond the
0 row. I was not able to figure out what this matrix is telling me or
if it is relevant to the problem I am experiencing.
Any help is greatly appriciated.
