JDK17 Extended Test Failures On test-osuosl-aix72-ppc64-5 due to filling /tmp

[steelhead31]

The JDK17 extended test suites failed when running on the test-osuosl-aix72-ppc64-5 due to filling /tmp.

The error can be seen here ( as well as in Nagios ) https://ci.adoptium.net/job/Test_openjdk17_hs_extended.openjdk_ppc64_aix_testList_2/

The test job appeared to create 2 x 2.1 GB tmp files in /tmp filling the entire file system, and causing tests to fail.

I am looking at all the systems - and as they are all recently cloned it appears there have been (undocumented?) changes to the system configurations.

When there are issues these should not be hacked at on the fly. There needs to be - at the minimum - reported in the issue what was done - and perhaps an update to the playbooks.

As an example: the size of 4G for /tmp was chosen because the test usedd to be smaller - and 4G was sufficient by nearly 2G. If the test is now doing 2x 2+G, obviously 4G is not going to work.

YET: when I look at the systems /tmp has not been increased, but /var has been increased on two systems.

I cannot second guess what needs to be done when changes are made on the fly.

So, no (known) action taken to resolve this issue. And it looks like it is just waiting to happen again - on different systems.

Seems to be affecting some, but not all systems: (note 100% used below).

• When I look at the affected systems - I wonder if the issue is caused, in part, by a lack of cleanup.

• I cannot conclude anything based on the file timestamp (last modified) - but I do see that the src.dat file is logically large, but physically small (ie, sparse).

• I'll increase /tmp to 5G to give breathing space, and cleanup junk
• If this resolves the issue - then the playbook can be adjusted to give /tmp 5G rather than 4G.

Looks like there may still be an artifact:

• Looking like it is not cleaning up properly?

• removed the files, and clearing jenkins.
• Is the last console output still available?

Just wondering if this is a problem with the test.

Needs to be examined further to determine in a clear environment, and ideally to narrow down which tests in the external suites are causing the problem.

OpenJDK have discussed test cases not always cleaning up after themselves.
