* Please also consider upgrade to Ubuntu squid3 package. 2.7 is not
maintained or supported for several years now.

  - NP: the caching support in the most current Squid is a lot better,
but I'm not sure the Ubuntu packaged version is new enough to include
all that. Either way the code is a lot closer to the currently supported
versions so tracing any issues and fixing them is a lot easier.

These are the defaults. In Squid-2 they are required to be present in
the config file.

How big is the drive?

This "no_cache" directive has been deprecated since Squid-2.4. Remove
the "no_" portion to see what it actually does.

Also, the "QUERY" ACL has been not needed (and a little harmful to HIT
ratios) since Squid-2.6. Consider removing those lines.

* Check the size of swap.state file in this directory. Also check the
log files directory.
   If you have a very busy cache they can all grow fast and Squid
requires more frequent "squid -k rotate" to clean up the swap.state
journal and log files. Even if you are using an external log manager
"squid -k rotate" is required to perform the related state cleanup and
cache journal management.

* Check this core dump directory to see if it is filling your disk with
lots of core dumps. If so please seriously consider the Squid-3 upgrade
and if the problem remains utilize the squid-3 core dumps to isolate the
issue.

   - Also if you can identify the directory squid is considering its
"home" directory on startup (*should* be the coredump_dir but not always
in the older Squid) check that directory as well.
