I´m running squid 2.6.21_07 on a Pfsense 1.2.1-RC2 and yesterday the proxy crashed. I checked the machine 4 hours before the chrash and it showed 2% disc usage. Then, suddenly 100%. So, on 4 hours the swap.state file had filled up 120gb with... something.
I deleted the file and rebooted the machine and everything runs again. But, I still dont know what caused the problem. Anyone got an idea? Or, have found a solution wich prevents it from happening again.
