Man, I empathize with you. Have you tried running Squid 3.4.x on FreeBSD 9.3? Sometimes I wonder if it's FreeBSD 10.x that's causing the issue...

I tried the shell variable MEMPOOLS=1 and that quickly made the situation a lot worse. Swap space would get filled up very quickly and the system would slow down quickly before crashing.

Any other ideas?
