I'm experiencing this weird issue with pfSense 1.2.3-RELEASE and squid 2.7.8_1, all of a sudden my disk is full and squid and related services stopped. As suggested in this same thread I was able to find out that my /var/squid/cache ballooned to 33GB for no logical reason, and as also suggested I've deleted said directory but after deletion my hard drive is still around 97% full and then 100% full again, how can this be correct if I've just deleted 33GB worth of space? After this squid stopped working then my hard drive free disk space was suddenly back to normal, this is really weird!
As last resort I did a windows thing (rebooted the box) and what do you know it's working again with disk capacity of only 9% which is normal.
Anybody experiencing this?
