By default, Tomcat assigned very little memory for the running process, you should increase the memory by make change in or catalina.bat file.

  1. Open “” file. is located at \tomcat folder\bin\
  2. Assign following line to JAVA_OPTS variable and add it into file.
    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
  3. Change the “Xms” and “PermSize” value base on your server capability.
  4. Restart Tomcat.
