Pool for Request structur doesn't stop growing

I have a problem with squid eventually consuming all swap space of the
server. from the cachemgr.cgi i can tell that the 'Pool for Request
structur' is the biggest memory user and keeps on growing. looking thru
the FAQ i didn't see any reference to this one. how do i put a limit on
it???
