Question

I am getting this error: “jmeter.control.GenericController: StackOverflowError detected” when I run my test. I am not able to understand why i’m getting this error.

I read a similar question on JMeter’s forum where someone has suggested to increase the ThreadStackSize to 4096. I’m running the test in Jmeter’s GUI mode. Where exactly should I change the ThreadStackSize? Is there some file in Jmeter’s /bin directory where I can change this property?

Look into your JMETER_HOME/bin dir, find there either jmeter file (unix shell – in case you are working with any unix/linux) or jmeter.bat (windows bat-file – in case you are using windows os).
In both your can find strings like:

HEAP="-Xms512m -Xmx512m"
NEW="-XX:NewSize=128m -XX:MaxNewSize=128m"
TENURING="-XX:MaxTenuringThreshold=2"
RMIGC="-Dsun.rmi.dgc.client.gcInterval=600000 -Dsun.rmi.dgc.server.gcInterval=600000"
PERM="-XX:PermSize=64m -XX:MaxPermSize=128m"
DUMP="-XX:+HeapDumpOnOutOfMemoryError"
SERVER="-server"
ARGS="$SERVER $DUMP $HEAP $NEW $SURVIVOR $TENURING $EVACUATION $RMIGC $PERM"
java $ARGS $JVM_ARGS -jar dirname $0/ApacheJMeter.jar "$@"

that define values of jmeter’s JVM params.

Simply add -XX:ThreadStackSize=4096 to any of these variables like

ARGS="$SERVER $DUMP $HEAP $NEW $SURVIVOR $TENURING $EVACUATION $RMIGC $PERM -XX:ThreadStackSize=4096"
java $ARGS $JVM_ARGS -jar dirname $0/ApacheJMeter.jar "$@"

or even

java $ARGS $JVM_ARGS -XX:ThreadStackSize=4096 -jar dirname $0/ApacheJMeter.jar "$@"

and restart your jmeter instance.
