 Seems to indicate that system factors may be involved , which may
 be unrelated to a native problem with squid :
 
   - check output of 'dmesg'
   - check /var/log/messages on a regular basis.

 Watch for weird messages, especially networking errors.

   - Check the Linux part of the squid fax, has anyone been
     tweaking with the system (checkout TCP ECN settings e.g)...

   - Check cache.log (squid), during problem window, watch for
     additional error info.
