Running BM38sp5 on NW65SP6. There are about 250 users and I have 2
traditional cache volumes of 2.5 Gb each. I'm using Craig's NW tuning
and also his proxy.cfg.

Box is newly built but every couple of weeks web performance grinds to a
halt and have to do a proxy -cc to get things running again. It looks as
if the cache volumes are running out of available directory entries, I
found a TID that suggested running vrepair so I will give this a try but
was wondering if there's anything else to look at as well. Is this
indicative of requiring more cache volumes?
