OutOfMemoryError: Java heap space. 1) An easy way to solve OutOfMemoryError in java is to increase the maximum heap size by using JVM options "-Xmx512M", this will immediately solve your OutOfMemoryError.
To fix it, increase the PermGen memory settings by using the following Java VM options. -XX:PermSize<size> - Set initial PermGen Size. -XX:MaxPermSize<size> - Set the maximum PermGen Size. In the next step, we will show you how to set the VM options in Tomcat, under Windows and Linux environment.
lang. OutOfMemoryError: PermGen Space is a runtime error in Java which occurs when the permanent generation (PermGen) area in memory is exhausted. The PermGen area of the Java heap is used to store metadata such as class declarations, methods and object arrays.
To increase the PermGen memory change the value of the MaxPermSize variable, otherwise change the value of the Xmx variable. There are a lot of answers similar to this around but I found that this was the clearest and simplest phrased, very helpful.
PermGen and heap size are different from each other.
You need to increase permgen space like this:
-XX:PermSize=256m
-XX:MaxPermSize=256m
add this flags.
Also look at this: explaining-java-lang-outofmemoryerror-permgen-space and this: how-to-deal-with-java-lang-outofmemoryerror-permgen-space-error
Hope this helps.

you need to set something in your tomcat argument
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"
Note:XX:MaxPermSize=256m
