Paul
Thank you. Currently thread max is at 1400. Strange thing is, this happens
on two pages where the user posts data repeatedly. Some of these IP
addresses also repeating in the log. And, there are no issues with the page
java code. In my previous setup, I did not gave this problem. I moved to
new box and I keep the same resin configuration. However, I  switched to
worker RPM in apache and using JDK 1.7 . I dont see any errors in resin log.


I tried to migrate 4.x version and getting the same problem.
thanks
Mani
