Struts 2.3.8 threads BLOCKED in
com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration
I'm load testing a web application on Tomcat 6 using Struts 2.3.8 version.
devMode is set to false.
I'm finding lot of BLOCKED threads in this method:
com.opensymphony.xwork2.config.ConfigurationManager.getConfiguration()
This is causing high CPU usage for the application. also find that
com.opensymphony.xwork2.config.ConfigurationManager.conditionalRelad is
taking time which causes getconfiguration (synchronized) to queue up for
processing.
This happens when concurrent users are above150.
Please let me know if anybody has a solution to this.

I think I found out the problem, could you register an issue and test
it after all?

Hi,
What do you use to profile your application? Is it possible to prepare
a snapshot of execution stack?
