X-based dashboards are running into issues quite regularly of late. Is this related to the QVTKOpenGLWidget changes?

The luigi issues are unrelated, as VTK was broken as well.
The vall issues looks like something we had during dev, but @shawn.waldon fixed it by reinstalling the nvidia driver as far as I know.
The drivers look fine right now as far as I can tell. I’ve unpaused the machine and we can see if the failures continue. I had to reboot the machine Friday since X was messed up. It was fine for a few builds and then these errors started to crop up again. At some point it got paused, but I’ve unpaused it and we’ll see how it handles the queue.
What Utkarsh is saying is that since the merge of the new widget the “X is messed up” type of dashboard error seems to be more common on both vall and luigi. Once X is broken neither VTK nor ParaView will work, but is the ParaView dashboard causing X to break?
Good question.
I will monitor luigi to see if the X breaking i see are related to the testing.
ParaView builds have been going for a while. I happened to look over and see a “Your OpenGL drivers don’t support the features required for basic rendering” on one of the ParaView tests.
So the pattern I see over the last day is that the tests were fine, then a few started failing on each build and finally everything failed. You can see this on my preset dialog branch if you look at the history on buildbot (the last 3 were all fine on other dashboards and locally).
Looking into the first build that failed and broke the streak of good builds on vall I tried to identify the first test failure that didn’t look related to the branch. Here is the build, and here is (according to buildbot) the first (temporally) test that failed that looks like a machine issue: https://open.cdash.org/testDetails.php?test=660266841&build=5406847
Test: pvcs.LagrangianParticleTrackerParallel

I’m seeing a simillar behavior on luigi.
serial tests are fine.
parallel test start failing, especially pvcs tests, then all tests fails with a segfault.
Somehow they sometimes recover.
I was able to get the segfault in gdb, here is the back trace :

This seems to be related to mpi and nvidia. but this trace is from a non parallel test.
I will try to get more info.
After a full update and a switch to ubuntu provided nvidia driver, I do not see the issue. I will keep monitoring.
After a night of testing, I have seen the same issue showed up. I will try to investigate more.
HI guys !
I have tested a branch that corrects a few memory errors that i have found with valgrind, but vall still seems to be not happy with it, we will see how luigi handles it.
https://gitlab.kitware.com/paraview/paraview/merge_requests/2511
I’m a bit out of my depth here. The fact that this issue is so elusive and only shows up in specific situations does not help much.
I have no idea how to make this move forward, could you take it from here ?
Here is the all the information I have gathered :
- After starting up the buildbot, no error
- After a few builtbot runs, between 4 to 10, nvidia driver error seems to appear
- error can be “GLEW could not be initialized” or the segfault mentionned earlier
- changing version of nvidia driver do not effect the bug (tested 384, 390, 340)
- changing version of Qt does not effect the bug (tested 5.9, 5.11)
- rebooting corrects the bug until it come back
- I could not test nouveau driver
- I did not test without MPI yet.
Another info point: the issue is indeed a “master” only issue. I had to run a couple of buildbots based off the release branch and all dashboards seemed totally happy:
e.g.
Indeed, as release does not contains the new QOpenGLWindow based code.
Here’s some interesting call-stack when quitting the application (this is from a custom app). I see a whole lot of makecurrent calls when quitting this custom app and it takes quite sometime to exit. I wonder if this is a clue.

That is indeed a bug in the implementation. Good find ! I have a fix coming. We will see if it improves.
pushed and test running :

I’ve updated my post, nvidia 340 did not help.
The makeCurrent fix seems to work so far. My need a little bit more testing to be sure.
Vall is still broken, even with master, so we can’t really take it’s results into account. @shawn.waldon

I’ve remarked that on luigi, used memory is very high after a round of testing with free output lilke this :
total used free shared buff/cache available
Mem: 11976 10234 953 45 788 999
Swap: 12246 0 12246
and no process is using the memory, while the computer is very slow if I run tests again.
It is of course fixed by a reboot, I wonder if this is related.
Vall has been rebooted.
