Subject Re: Tomcat current thread count
Date Fri, 25 Jun 2010 14:31:27 GMT

My system consists of:

Rhel 5.3
Tomcat v 6.0.26
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)

I do not see anything else in the catalina.out or any other log file apart
from the one I have posted before.
What would be the possible ways of finding where the problem lies ?
