Saw the X server issue while running tests on https://github.com/eclipse-openj9/openj9/pull/17243 TestFailure link: https://openj9-jenkins.osuosl.org/job/Test_openjdk8_j9_sanity.functional_ppc64_aix_Personal_testList_0/203/

Few things to note:

The tests were running with AOT
Running the test on other nodes succeeded.
In the failed testcase X server was started (See https://github.com/eclipse-openj9/openj9/pull/17243 for Peter's comments)

Also of interest is that I tried to recreate it on the machine where it failed but could not. https://github.com/eclipse-openj9/openj9/pull/17243#issuecomment-1542625365

I don't think it's a real problem, just some kind of temporary network/machine issue.

I'll keep this open for a while in case it's seen again.
