intermittent failure (yes):
regression or new test: N/A

Occurs periodically on AIX AOT tests; see #14894 (comment). This error has been happening for a while; opening this issue to give reviewers something to refer to in order to justify merging PRs where this error shows up in PR builds.

Number 8 appears to have X11 installed correctly. Is this intermittent or does it always fail?

pshipton · 2022-08-30T18:25:23Z

Seeing more of these today, did something change?

Number 8 appears to have X11 installed correctly.

Perhaps having X11 installed correctly isn't the problem. Is it running?

ymanton · 2022-08-31T14:26:03Z

Saw this while testing #15683

I think the X server may not be handling client disconnections properly, or clients are not disconnecting properly on AIX.

While running a grinder I noticed that in each iteration we try to start an X server without stopping the previous one. The first test run successfully connects to the newly started X server:

Subsequent iterations try to start a new X server but that fails because the first is still up and listening on the port.

I can't tell from the existing output what the problem is, but there might be something in the X server log, if someone can get access to it.

pshipton · 2022-08-31T21:29:20Z

@llxia can someone take a look at this pls.

llxia · 2022-09-01T18:08:09Z

Sure, we will look into this.

llxia · 2022-09-07T15:00:25Z

I can only reproduce this issue when setting iterations as we repeatedly start an X server within each iteration. So far, I am not able to reproduce the error when repeatedly triggering new jobs on the same machine.

ITERATIONS=5: Grinder/27199/
1st iteration passed and the rest failed with the expected error - Exception in thread "main" java.awt.AWTError: Can't connect to X11 window server using 'unix:0' as the value of the DISPLAY variable.
same Grinder job with ITERATIONS=1 right after and it passed: Grinder/27200

I will move x11 cmd out of the loop. And I suspect that we do not need nohup in the cmd.

- move x11 cmd outside of iterations - remove nohup in x11 cmd - only start x11 for BUILD_LIST=openjdk, jck and/or functional Related: eclipse-openj9/openj9#14943 Signed-off-by: lanxia <[email protected]>
