If same user does not expose the difference, start the test script from the 
directory where you told Squid to dump core.

Shell Output - /var/log/squid/try.sh
sh: /var/log/squid/try.sh: Permission denied
I can’t run it I have set it to chmod 777 and running it as root.
I do not have the sudo enabled currently however I wonder if I add root to the 
/var/log/squid it that would fix it

Glad you have a working "sanity check" test! I agree with FreeBSD forum 
folks that you have proven that your OS does have core dumps enabled (in 
general). Now we need to figure out what is the difference between that 
working test script and Squid.


Please start Squid from the command line, with -N command line option 
(among others that you might be using already), just like you start the 
"sanity check" test script. And then kill Squid as you kill the test script.


If the above does not produce a Squid core file, then I would suspect 
that Squid runs as "squid" user while the test script runs as "root". 
Try starting the test script as "squid" user (you may be able to use 
"sudo -u squid ..." for that).


If same user does not expose the difference, start the test script from 
the directory where you told Squid to dump core.



HTH,

Alex.


I have tested it with a sanity check with the help of FreeBSD 
forum users. However it just does not show a core dump for me on 
anything kill -11 kill -6 killall or kill -SIGABRT. I have it set in the 
config to use coredump directory also

On Unix-like systems, the command to send a process a signal is 
called "kill": https://www.man7.org/linux/man-pages/man1/kill.1p.html


For example, if you want to abort a Squid worker process that has OS 
process ID (PID) 12345, you may do something like this:


  sudo kill -SIGABRT 12345

You can use "ps" or "top" commands to learn PIDs of processes you 
want to signal.

Beyond using a reasonable coredump_dir value in squid.conf, the 
system administration problems you need to solve to enable Squid core 
dumps are most likely not specific to Squid.



HTH,

Alex.


It’s funny as soon as I enabled the sysctl command and set the 
directory it won’t crash anymore. I also changed it to reside on the 
loopback before it was only on my lan interface. I run an external 
drive as my swap partition or a swap drive, it works I get crash 
reports when playing around with stuff. /dev/da0 or something it 
dumps to it and when it reboots shows in the var/crash folder and 
will display on gui report ready, again if anyone else knows pfSense 
let me know. I also added an item to the Netgate forum to, but not 
many users are Squid wizards so it might take a long time to get any 
community input over there.

You know what it was, it needed to be bound to the loopback and not just the
