I had a problem with Squid which required removing the access.log file as it had grown over 2Gb in size which has caused Squid to terminate and also stopped Squid from starting.
The cache.log file seemed to hang at:
2008/04/20 19:09:23| Ready to serve requests.
2008/04/20 19:09:24| Configuring Sibling cache2.domain.tld/8080/3130
2008/04/20 19:09:24| Store rebuilding is 1.4% complete
Earlier in the logs I found:
FATAL: logfileWrite: /path/to/squid/logs/access.log: (0) Success
Squid Cache (Version 2.6.STABLE5): Terminated abnormally.
