Details

Application server, Windows server, Tomcat integrated with Eclipse

Problem Clarification

Tomcat server down after running 2-3 hours, "outofmemory" "cannot create new native threads" error messages shown in catalina logs.

Application server cannot reply MPP's requests that cause inbound calls failure.

Cause

Tomcat JVM memory is not enough, maximum heap memory is set to 260M. Tomcat used up the memory and crash.

Solution

For Eclipse-integrated Tomcat, if you start it from Eclipse, it will use the JVM parameters on Eclipse, not the Tomcat configuration files. So change the maximum JVM memory on tomcat configuration will be not applicable for this case.

We should change the settings on Eclipse:

Window-> Preference-> Installed JREs -> Edit -> input "-Xms256m -Xmx1024m" for "Default VM arguments".
