Tomcat – Java.Lang.OutOfMemoryError

Apache Tomcat server may spit this error. To solve this error you need to update catalina.sh file.

1. Locate catalina.sh in bin directory. (Eg : apache-tomcat-7.0.22/bin/catalina.sh).
2. Edit it and append this line,


JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"

3. Save file and restart the server.

Thats it.
