Debugging stuck vdsm jobs

Hi all, We had 2 issues causing vdsm check-patch and check-merge jobs to get stuck. I fixed the one that caused most trouble: https://gerrit.ovirt.org/57993 The other issue may be related to ioprocess, I fixed a related issue: https://gerrit.ovirt.org/57473 But I have seen stuck jobs after this change, so the issue may not be fixed yet. If you see a stuck vdsm job - job that run more than 15 minutes, please get me a backtrace: 1. locate the test_runner process pid: $ ps aux | grep testrunner.py | grep -v grep nsoffer 26297 82.6 0.9 389592 111144 pts/3 R+ 22:52 0:02 /usr/bin/python ../tests/testrunner.py ... 2. save a backtrace: gdb attach 26297 --batch -ex "thread apply all py-bt" > py-bt.out Thanks, Nir
