This is not directly related to too many open files, but to too many  
processes running. I presume your login shell is bash. The you can  
invoke in Terminal

	ulimit -aH
	ulimit -aS

The former command will report the "hard" limits which cannot be  
altered so easily. The latter command reveals all the "soft" limits  
that you can raise up to those hard ones. This can be done  
automatically at login time, for example in ~/.profile.

I think you should be able to raise the number of running processes  
when you're already logged in (ulimit -u <number>) ...



We are usually convinced more easily by reasons we have found  
ourselves than by those which have occurred to others.
