yep, i figure that we show several GB of free RAM and many GB of free swap.
if we have 8MB more stack space per PID and about 100 PID's on the box then my math says we may be using about 1GB more RAM if we change the stack size.

we have a strange database program that has been giving a "cant fork" error for some weeks, when we put ulimit -s 16384 in the startup script it solved the problem.

but now when we do a lookup or search using the command line tools we also get a "cant fork", if we put a ulimit -s 16384 before we do the command line stuff we are OK again.
