            Bug ID: 195802
           Summary: squid restarts after shutdown and dumps core
           Product: Ports Tree
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: freebsd-ports-bugs@FreeBSD.org
          Reporter: la5lbtyi@aon.at

Scenario:
  - squid-3.4.9_1 and adzap-20110915_1 are installed
  - After starting squid, the PID in the pid file points to squid's first child
process:

[0]# cat /var/opt/squid/run/squid.pid 
62002
[0]# pstree | grep squid
 |       \--- 62371 root grep squid
 |-+= 62000 squid /usr/local/sbin/squid -f /etc/opt/squid/squid.conf
 | \-+- 62002 squid (squid-1) -f /etc/opt/squid/squid.conf (squid)
 |   |--- 62003 squid (unlinkd) (unlinkd)
 |   |--- 62004 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62005 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62006 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62130 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62131 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62132 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62133 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62134 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   |--- 62135 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
 |   \--- 62136 squid /usr/local/bin/perl5.18.4 -w
/usr/local/libexec/squid_redirect
[0]#

Problem:
  - Executing "service squid stop" initially stops process 62002 (the first
child process) and all its children, as a side effect producing a core dump in
the cache directory. Immediately thereafter, the process is restarted again,
with a new PID which is duly recorded in the pid file, and spawning all the
other subprocesses (squid_redirect).

Expected outcome:
  - After executing above command, squid should shut down completely, and no
core dump should be produced.
