700 threads!  It would be best to fix your code so you don't require
that many threads.  (Unless of course you have 512 CPUs.)

You're probably hitting the 'max user processes' limit - it applies to
threads as well.  Try 'ulimit -a' to see it (but I thought Linux-2.4
basically had no such upper limit any more).
