------------------------------------------------
Is this failure related to the patch or was it found in Trunk builds?
In following trunk builds the test case successfully passed after changes to {{TestKillSubProcesses}} were put in.

-----------------------------------
Just a while back, even I've encountered the same issue. Unfortunately I didn't back up the logs. Will do so the next time.

-------------------------------------------------
I have observed it in one of the patch builds, in which patch is not related to the testcase. Looks like it is a timing issue.
