server runs out of memory

NW6sp5 IBM server with 2 Gig RAM runs out of memory. Perhaps I should ask in
the BorderManager group. The server is running BM3.7sp3 and the Connectotel
blocks, Adwall, Linkwall and Filewall.

I have been working on this problem for a while now. I've followed every TID
I could find. I have not identified the NLM which is eating up the memory,
but the memory allocation starts out with 55% allocated to cache and by the
time it has the problem that much is allocated to NLM's.

Any help is greatly appreciated.
