I'm testing Dan's Guardian at home in hopes to use it in a school.  All seems to be working ok but I'm having a problem with memory.  The cache uses all my memory after a few days and then I can't get to the net.  I reboot the box and all is good again for a while.  Any ideas/suggestions??
Thanks,
Rick
