server.xml is with below configurations

connectionTimeout="20000" maxThread="150"

There are thousands of client concurrently accessing tomcat server

Note: Not able to reproduce the above case, Sometimes this exception occurs

Exception occurred after reaching 20seconds (connectionTimeout) in server.xml
