Hello Sergiu,

an interesting observation...

Of course, disabling the run-log is not an acceptable option.

We need a thread dump to analyze the deadlocked application. The
easiest way to get it is using a nice little tool which is available
online. You can find and directly start it as Java WebStart
application from

then go to "Download".

After starting the tool, thread dumps can be generated via menu
"Process->Thread dump". In case you are not sure which Java process
represents your SUT, simply send thread dumps for all processes.
Especially in this case it would be good to get a dump of QF-Test as

Please send the dumps directly to us, don't bother the list with them.

Best regards,
