Run away number of smbd children

I am not real familiar with smbtorture memory requirements, but when our
engineer set up the test she used a number of clients and spread out the
instances amongst them.  I think this will torture SMB more anyway :)

You are using the SMB 4 version of smbtorture correct?

I've setup a fully loaded 1280 (SunOS cavern 5.10 Generic_125100-10 
sun4u sparc SUNW,Netra-T12) with samba 3.0.27a and 4's smbtorture; 
however, I can't get the torture app to open more than 251 connections 
before I get memory errors.  This box has 24GB memory!  Should I point 
several machines+smbtorture at it or is there some memory setting that 
I've over looked?
