@ashbm5 can you pls take a look

alon-sh commented 4 years ago

@shanchao95 please try to reproduce

shanchao95 commented 4 years ago

I tried to re-run the tests with same parameters on Grinder, and tried to run the test9a.java locally with jvm from https://140-211-168-230-openstack.osuosl.org/artifactory/ci-eclipse-openj9/Build_JDK8_ppc64le_linux_Personal/655/OpenJ9-JDK8-ppc64le_linux-20200122-162742.tar.gz. Did not see it occur again. Here is tests results on Grinder https://ci.adoptopenjdk.net/job/Grinder/2157/.

pshipton commented 4 years ago

On the open machines, grinders on ub16-ppcle-2 (1x), ub16-ppcle-3 (5x) didn't reproduce it, but grinders on ub16p8j92 and ub16p8j95 did. https://ci.eclipse.org/openj9/view/Test/job/Grinder/631/ https://ci.eclipse.org/openj9/view/Test/job/Grinder/632/

pshipton commented 4 years ago

@jdekonin are there openssl updates not installed on the ub16p8j9x machines? If you do update the machines, pls record the original level and the updated level.

jdekonin commented 4 years ago

Updates to both sets of machines were going to occur on a scheduled "maintenance 1/2 day". But that date hadn't been set. ub16-ppcle-1 -> ub16-ppcle-3 are on 1.0.2g-1ubuntu4.15, the systems have 135 packages to be updated, 6 are security updates. ub16p8j91 -> ub16p8j96 are on 1.0.2g-1ubuntu4, the systems have 384 packages to be updated, 161 of which are security updates.

If you are in agreement that these can be rotated through tomorrow @rajdeep-singh and I can proceed, just advise if we should be doing an full system update to bring them all current, or if we should just be performing an openssl update.

pshipton commented 4 years ago

We can do a full system update, but let's only do one system of each ppcle and p8j9 first and make sure they are still working fine afterward before doing the rest.

jdekonin commented 4 years ago

ub16p8j91 and ub16-ppcle-2 have been updated to the latest levels and brought back online. Note that ub16-ppcle-2 also had an issue with protobuf.

pshipton commented 4 years ago

Confirmed the crash still occurs on the upgraded ub16p8j91 https://ci.eclipse.org/openj9/view/Test/job/Grinder/638

pshipton commented 4 years ago

@jdekonin what is the openssl version after the update?

jdekonin commented 4 years ago

ub16p8j91 is at 1.0.2g-1ubuntu4.15, same as ub16-ppcle-2.

M-Davies commented 4 years ago

This is also occurring at Adopt. Last nights JDK14/j9/aix run on tests

There is a fix underway for this https://github.com/ibmruntimes/openj9-openjdk-jdk8/pull/381 https://github.com/ibmruntimes/openj9-openjdk-jdk11/pull/283 https://github.com/ibmruntimes/openj9-openjdk-jdk14/pull/34 https://github.com/ibmruntimes/openj9-openjdk-jdk/pull/185

pshipton commented 4 years ago

This is an intermittent problem tracked in a Milestone. I'm going to dissolve the "Blocking sanity.openjdk" project since the less intermittent problems were resolved by reconfiguring sanity.openjdk to tier1.

pshipton commented 4 years ago

The fix https://github.com/eclipse/openj9/issues/8373#issuecomment-603814836 is merged, but not yet into the 0.20.0 branch.

pshipton commented 4 years ago

The updates to the 0.20.0 branches are complete.
