JMeter's JVM crashes after 10 minutes

Vishwas Trivedi :

I'm using JMeter with 10 slaves. After executing for 10 minutes java crashes:

# A fatal error has been detected by the Java Runtime Environment:

I recently had to increase Java heap size for all the slaves and server machine due to OutOfMemoryError. all 10 slaves has 4GM RAM and server machine has 16GM RAM. Current JMeter settings are : HEAP=-Xms512m -Xmx3276m

user7294900 :

You are working with Java 8, but still using an old JMeter 3.1 version,

Please try to use latest Version 5.0 which is the first listed in JMeter best practices, and also for your issue, reduce as much resources as possible:

Use non-GUI mode: jmeter -n -t test.jmx -l test.jtl

Use as few Listeners as possible; if using the -l flag as above they can all be deleted or disabled.

Don't use "View Results Tree" or "View Results in Table" listeners during the load test, use them only during scripting phase to debug your scripts.

Rather than using lots of similar samplers, use the same sampler in a loop, and use variables (CSV Data Set) to vary the sample. [The Include Controller does not help here, as it adds all the test elements in the file to the test plan.]

Don't use functional mode

Use CSV output rather than XML

Only save the data that you need

Use as few Assertions as possible Use the most performing scripting language (see JSR223 section)
