The probe's Java memory limits can be configured through the probe's Raw Configure GUI in the options key under the Startup section.
The default options value is:
-Xms32m -Xmx512m -Duser.language=en -Duser.country=US
As long as memory is available on the robot where the vmware probe is installed, you can resolve this problem by increasing the Java memory limits. We typically recommend doubling the values:
-Xms64m -Xmx1024m -Duser.language=en -Duser.country=US
After saving and then applying this configuration change, you must deactivate and then activate the probe to put this change in place.
