This is normal. Ideally, you should configure your gdb to ignore SIGHUP
and pass that signal to Squid.

Thank you for posting your stack trace there. You did the right thing.

Please try the patch for bug 4864. That bug may be a duplicate of bug
4896, and it has an unpolished/unofficial fix:

  https://bugs.squid-cache.org/show_bug.cgi?id=4864

Please update bug 4896 to let us know whether bug 4864 fix worked for
you (including cases where the posted patch no longer applies).


Thank you,

Alex.
