I'm running some stress tests against an environment that has the following configurations
Liferay 6.0.11 on top of Tomcat 6.0.32
Apache and Tomcat are configured to connect to each other using the AJP protocol. At some point of the test I got a message in Tomcat log as below:
GRAVE: All threads (200) are currently busy, waiting. Increase maxThreads (200) or check the servlet status
I'm not pretty sure but this seems to be due the Tomcat 6 does not have AJP built with support for NIO, right? Is there a workaround for this? Should I move to Tomcat 7 http://www.tomcatexpert.com/blog/2011/06/17/apache-tomcat-7016-released?
