The only way to make him response againfor a while is to reboot the machine.
i use Squid Cache: Version 2.5.STABLE3-20030825
Configured with this options.
configure options: --enable-delay-pools --enable-removal-policies=lru,heap
--enable-storeio=ufs,aufs

This is my internal proxy.
My external proxy works just fine(Compiled with Same Options).
what could be wrong?
They both run on Redhat 9.

thanks in advance
