Description
When trying to integrate https://codereview.qt-project.org/#/c/195904/ we observed several times that tst_qprocess::lockupsInStartDetached sometimes hangs.
Backtrace is attached.
On a RHEL 6.6 coin VM I could reproduce the hang with commit 15fe60cfdada84ea519f08e905d59cc3fb6d20cd already by running the single autotest in a loop. According to the failure logs it's not specific to RHEL though.
Non-scientific impression: When the CI was under heavy load I was able to reproduce the hang after 50000 runs or so, in quieter times it took several hours (15 or so) running in a loop.
I've attached three strace logs:
- normal run (not hanging)
- hanging
- hanging after pressing Ctrl-C
