I was thinking of #1529 a 3.0-pre bug sorry not 2.6*. Sounds like a
similar effect despite the version.

  Which squid are you using?

  Are you closing squid through a custom script sending SIGHUP/kill to a
pid or a ports script provided by an official maintainer?

A custom script may still encounter problems if it handles RunCache
badly. Could be KILL'ing the child squid worker instead of HUP'ing the
RunCache control process.
