      Description

        Since ~ 25th August we see the test TestDumpOnCrash.java failing on Linux ppc64le and Linux aarch64.
        It reports the following :

        Attempt 0. Verification failed:
        File length 0. Should at least be some bytes: expected 0 to not equal 0
        Retrying...

        Attempt 1. Verification failed:
        File length 0. Should at least be some bytes: expected 0 to not equal 0
        Retrying...

        Attempt 2. Verification failed:
        File length 0. Should at least be some bytes: expected 0 to not equal 0
        Retrying...

        java.lang.Exception: 3 attempts with failure!

        So 3 times an "evacuation" file of 0 bytes is reported .

        The test "generates" crashes when trying to test the jfr "evacuation".
        But in these crashes I notice timeouts like these :

        [thread 76208 also had an error]

        ------ Timeout during error reporting after 120 s. ------
        # [ timer expired, abort... ]


        Is it maybe related to 8242181: [Linux] Show source information when printing native stack ?
        That might change the crashing behavior in Linux ?
        Should the timeouts be increased somehow for this test ?

        The test machines showing the issue are based on SuSE SLES15 and RedHat 8 so the kernel should be not that old.
