I have squid 5.3 running on amazon linux 2 and it was running fine for some weeks until it suddenly stopped working yesterday on our production server and caused outage. I have set it to auto-restart for now. But if someone could review my squid.conf file and see if there is something wrong?
This is the error I saw===
2022/04/06 00:45:31| FATAL: xcalloc: Unable to allocate 1 blocks of 68431 bytes!

2022/04/06 00:45:31| Squid Cache (Version 5.3): Terminated abnormally.
