[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: query regarding the thread pool size in JBoss

[puneetjain]

Appreciate your valuable inputs.

We are not using web services to EJB through JMeter.

We are wondering if thread pool size not affecting the performance could be becuase we are using jboss-4.2.2.GA free/open source version.

We are not using commercial version of JBoss for the development.

We seeing following errors in the log files when there running throug JMeter for 500 threads and 2 loops:
