Hi - 

Here's one for the NWSAA experts.

We're running NWSAA 2.0.30 on Netware 3.12 on a 486.  Hostprint 1.11 is also 
running on the same machine.   The server runs pretty exclusively SAA, with 
very little file/print activity.  

We started out with 16M memory.  When the server was brought up, the Cache
Buffers stood at about 43%, and the Alloc Memory Pool was somewhere under 2
MB.  Suddenly, with no console message, the Alloc Memory Pool jumped, eating 
up all the cache buffers, leaving us with 1%, until the server crashed.  The
wierd part of it is, out of the 7 MB of Alloc Memory Pool, less than 2 MB
were in use.  What happened to the other 3 MB?  I presume these were supposed
to return to the Cache Buffer pool but never did, right?

Next step - SET MAXIMUM ALLOC SHORT TERM MEMORY=2500000.  But that also 
crashed the server.  Some process or NLM must have been looking for memory,
and couldn't get any.

To test the problem further, we added another 16 MB memory.  Once again, 
the Alloc Memory Pool started out at less than 2MB.    Yesterday morning, 
I came in and found the Alloc Memory Pool at  * 15,992,208 *   But, as 
before, less than 2 MB were in use.  So I have some 13 MB of memory 
unaccounted for.

The statistics in Monitor don't seem to reveal much.  The sum total of 
Alloc Short Term Memory (Bytes) seems to total the amount of the Alloc
Memory Pool in use - 2 MB, not the grand total of almost 16 MB.   So 
the bottom line is - where has all my memory gone?

All the NLMs are the latest versions, and I'm running all the latest
patches from Novell.  This problem is only on the SAA server.  We're 
running 30 other 3.12 servers on the campus, and haven't seen this kind of
problem anywhere else.  I know that Novell 4.10 handles memory better.  It
has a "garbage collection" process which might be built for just this kind
of problem.  We will ultimately be upgrading this server, along with all
of our others.  But we're not ready just yet, if we don't REALLY have to.

Any ideas?
