OutOfMemoryError in JMeter

Question

In JMeter I am getting this error.

jmeter.JMeter: Uncaught exception:  java.lang.OutOfMemoryError: Java heap space

Please let me know how to resolve.

Answer 1

Increase the JMeter heap memory

1. Within your explorer find where you installed JMeter
2. Open up the bin directory.
3. Find the JMeter.bat file and open it with a text editor
4. Find the following set HEAP

   You can set this HEAP value to whatever you like, in this example I've said allocate 2 GB of memory from the start and throughout the test run: set HEAP=-Xms2048m -Xmx2048m
