@ymanton Have you seen this before

[cjjdespres]

This is also showing up in the internal JITServer tests, e.g., in https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk17_j9_sanity.functional_x86-64_linux_jit_Personal/923/.

Also seen on s390x: https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk17_j9_sanity.functional_s390x_linux_jit_Personal/832/.

Sorry, missed this mention.

I've seen this error before, but it can be caused by many different kinds of problems. We need a more verbose CRIU log to understand what happened before the errors, although even that isn't always enough info.

I'll open a PR to make the logging more verbose and we can go from there.

This one is odd in that lots of CRIU tests succeeded, but a handful failed, however the syscall causing the issues is always executed and I don't see any documented reason why it would fail intermittently.

Is this a machine problem, unsupported OS? The test was running on Ubuntu 16. They always fails on Ubuntu 16, see #18994 (comment) for a short list and then I stopped reporting them.

Also Jason opened #19211 for the same issue on SLES 12.

The internal failures mentioned in #19114 (comment) are actually https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk17_j9_sanity.functional_x86-64_linux_jit_Personal_testList_1/913/ and https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdk17_j9_sanity.functional_s390x_linux_jit_Personal_testList_0/809/, which are both running on SLES 12.
