Squid 3.3.10 v 2.2.2 crashes every 4 days high memory usage in GUI

  • I am running squid3-dev 3.3.10 v 2.2.2 on Intel E2180 with 2GB DDR2 ram, 80Gb HDD on pfsense 2.1 amd64 along with qlproxy 3.2 amd64. I have 80 computers behind this firewall with 8mbps Wan speed. My local cache settings for squid are

    hdd cache : 16384 Kb
    level 1 subdirectories : 32
    minimum object size : 0
    max object size : 32

    Memory cache : 512mb
    max object size in ram : 32kb

    I have a strange problem. I start receiving icap protocol error every 4.5 days, Every day the gui memory usage keeps on increasing , it starts with 27% after a reboot and reaches 93% after 4.5 days after which I start receiving icap protocol error. restarting squid and qlproxy works for only a few minutes and the error starts again, Finally I have to reboot the firewall every 4 days else squid does not work.
    Any hint to resolve this problem?
