Hello,
I am running squid as http caching server, after running for few days
our squid server will stop responding to client requests.
When this occurs, I see below errors in cache.log.

Summary : The Squid proxy caching server
URL : http://www.squid-cache.org
License : GPLv2 and (LGPLv2+ and Public Domain)
Description : Squid is a high-performance proxy caching server for Web clients,
: supporting FTP, gopher, and HTTP data objects. Unlike traditional
: caching software, Squid handles all requests in a single,
: non-blocking, I/O-driven process. Squid keeps meta data
and especially
: hot objects cached in RAM, caches DNS lookups, supports
non-blocking
: DNS lookups, and implements negative caching of failed requests.
:
: Squid consists of a main server program squid, a Domain
Name System
: lookup program (dnsserver), a program for retrieving FTP data
: (ftpget), and some management and client tools.
