Hi Ivan,

Solaris 10 has more stringent ulimit(open files).  ulimit -a shows the
limit you have.  The limit is per process - so a threaded model uses all
file descriptors in one process and the pre-forked model does not.  I
think your problem is solved if you increase your ulimit(open files) to
a large number (say 16384) with

$ ulimit -n 16384

Building with sun-studio does not change the ulimit enforced.

Best regards,
   Wouter
