$ exited due to signal 6
After lots of logs reading and net hunting i found out that this error was corrected on a newer version of squid.
The error was on the following version:
Squid Cache: Version 2.5.STABLE6
I upgraded to:
Squid Cache: Version 2.5.STABLE11
So i upgraded and .... no more crashes.
Some tips and commands that helped on troubleshooting:
Read squid logs:
- /var/log/squid
- cache.log
Verify squid cache directory:
- /var/spool/squid
Verify message logging:
- /var/log/messages
Commands:
to rebuild cache: squid -z
to start with debug: squid -d 3 -F -N -X
-d 3 --- more debug level
-F --- don't service any request until cache is rebuild
-N --- no daemon level
-X --- force full debug
