In most cases you'll need to run squid from within an debugger.
I use a script for that:
========================
#!/bin/bash
rm /var/run/squid.pid
echo 512 > /proc/sys/kernel/msgmni
ulimit -n 262144
ulimit -c unlimited
ulimit -v 85000000
backtrace=`mktemp`
outfile=`mktemp`
gdb -q -x /etc/service/squid5/gdbcommands /usr/sbin/squid 2>&1 >$backtrace
cat $backtrace | \
/usr/bin/mail -s "`hostname`: Squid wurde beendet" Ralf.Hildebrandt@xxxxxxxxxx
rm $backtrace
rm $outfile
The file /etc/service/squid5/gdbcommands contains the commands for the
GDB debugger:
# snip
set args -NsYC
handle SIGPIPE pass nostop noprint
handle SIGTERM pass nostop noprint
handle SIGUSR1 pass nostop noprint
handle SIGHUP pass nostop noprint
handle SIGSEGV stop
handle SIGABRT stop
run
set print pretty
backtrace full
generate-core-file
quit
# snip
I hope this helps.
