The Max Threads for Tomcat should be increased from inception, as it is originally set to a low value (75) by default.
The recommended size is of 150 to 300 and it's changed in file server.xml. This document provides the Steps to do the same.
Here are the revised steps to increase the number of Tomcat threads:
- Take a backup copy of the server.xml file from NX_ROOT/bopcfg/www/CATALINA_BASE/conf.
- Open server.xml file from NX_ROOT/bopcfg/www/CATALINA_BASE/conf with a
text editor. Find the appropriate "connector" section and set maxThreads to 300.
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1"
<Connector connectionTimeout="20000" port="8080"
- Restart Tomcat:
