Wow. What a rookie I've turned out to be. I hadn't even considered that being the reason for Squid shutting off. Thankfully I haven't hit that in a very long time. You are correct, both Squids were affected by their access.log file being 2147483647 (2^31 -1) bytes in size.

Now I'm off to look at the FAQs, etc, on perhaps compiling Squid w/ large-file-access..

Thanks, Henrik, you always come through.

Recently I had two of our four Squid [1] proxy servers die. What appears to have happened is a user was making requests to the proxy so quickly, that it died with the following message.

FATAL: logfileWrite: /var/log/squid/access.log: (11) Resource temporarily unavailable

A quite common cause is access.log reaching the magic 2GB barrier of
32-bit applications..
