Thanks for your reply
first, i have about 200,000 users but there is some thin g in the
configuration that makes the users connects and disconnects in less
than 15 minutes , and that makes that huge number of requests
(it's a temp. situation ) of-course.
second i tried the configuration you sent.
the server didn't start, so i guess it OS problem as you said but how to
fix it ??
can you help me with that ??
