It'd be ncie to know what that is, but no, that in itself shouldn't hang
browsing activities.

Well, squid is using bugger all memory then.

Debugging this will require a little more effort.. you will probably
have to begin by fiddling with your server stats and determine what else
is going on. You may want to run the system call tracer on Squid to see
what its doing when it slows down to see whats going on.

This sort of stuff is precisely why I suggest people graph as much about their
Squid servers as they can!
