Hi Thomas,

thanks for taking a look and for sponsoring. I put the test in our internal test system and it passed on all our Linux platforms, AIX, Windows 64bit and Solaris. I think 64m should be fine. Linux on ARM64 and macOS did not run yet but I expect no problems.

Best regards,

Hi Arno,

Seems reasonable, assuming you verified that 64m heap are enough for this test on all platforms.

I can sponsor this for you.

Cheers, Thomas

I have seen some occurrences of this issue (8230110) on our AIX and Windows test machines. The test times out because it writes a huge core file (I have seen more than 24GB on one machine) and this might take minutes.
As far as I understand the test does not need a core file. Therefore my suggestion is to set a max java heap size (-Xmx64m) and switch of core file writing (-XX:-CreateCoredumpOnCrash).

I am no committer – I will need a sponsor for this change.

Best regards,
