[Brahms-dev-l] proof problems

Brahms,
  I have not been invloved in any discussions about proof, but we do have a major problem with memory.  Last night I ran a proof session which died on me because it used up all the available memeory.  Now there was nothing special about this session other than I was testing out my code.  Now there could be somehting wrong with my code, but this does not explain why a proof session uses up more and more memory when I do NOTHING!!!  
Now if I want to load in a number of libraries, I'm using up more memory at the start.  

Yesterday I ran over all the auau 200GeV data filling a number of histograms.  I created 8622 histograms (a good number of them were not filled with any events) in a proof session.  The session ran fine.  

Last night, I ran another session to test some code and I tried to process all of the auau 200GeV data.  I created 11 histograms, loaded in a library, and the proof session hung with a memory leak.  Here is the responce I got from RCF

OK - I'll reboot some of the nodes that are still down but Brahms
needs to come to grips with how to run proofserv.  You can't
expect to run multiple proofserv processes >1.7GB each without 
driving swap down to ZERO, even with 2G of memory, possibly crashing it.
If this occurs on a weekend, you will have to wait until Monday.

Open to suggestions if there is anything we can do at this end.

Now does anyone have a good idea on how one can approach and fix this problem?
Erik
