Test run aborted

Execution failure. No status received from location computername in interval seconds.
The workbench has lost communication with one or more
agent computers.
The test run stops.
For each agent computer:

Check that the playback Java™ process is running. If it is still running, the problem might be
on the workbench computer. Stop the Java™ process and all related typeperf and vmstat processes.
Examine the problem determination log for error messages or exception
messages.
If the playback Java™ process
is not running, search for javacore.* files.
The contents of these files might help you determine the cause of
the problem.
Run tests again and monitor the memory size of the playback Java™ process. If the playback Java™ process is consistently running
at its maximum heap size, the process might not have enough memory.
If the problem is not on an agent computer, check that the
workbench computer has sufficient memory. To increase the available
memory, either increase the workbench heap size or reduce the level
and amount of execution history.
