5000 threads might be a little excessive, depending on what your application is doing and how much memory a thread consumes versus how much resource the physical machine has. 789 errors for only 81Mb sent seems a little high. Are you load testing or is this in production? How much memory does the machine have? How much is allocated to Tomcat? What operating system is it? p > Tomcat Version:Apache Tomcat 5.5.20 > Java JRE 1.6.0 > > Regards > rujinraj >
