Matthias Pohl commented on FLINK-32534: --------------------------------------- The failure you describe happened on agent {{AlibabaCI008-agent05}} on Jul 03 at 11:07:41. I checked the CI builds you reported in FLINK-18356. There is a 137 exit code CI failure (you reported it in this comment) in the {{flink-table}} module on {{AlibabaCI008-agent02}} (i.e. same VM) on Jul 03 at 11:07:07. The 137 OOM errors make all the JVM processes crash on the same machine. We've seen this in the past where there was always a CI build failing in {{flink-table}} involved. That brought us to the conclusion that FLINK-18356 is the most-likely reason for the OOM. Therefore, you might want to close this Jira issue as a duplicate of FLINK-18356 (it's important to link the Jiras to make sure that we can trace back issues in case the OOM is not only caused by FLINK-18356). > exit code 137 (i.e. OutOfMemoryError) in flink-tests module > ----------------------------------------------------------- > > Key: FLINK-32534 > URL: https://issues.apache.org/jira/browse/FLINK-32534 > Project: Flink > Issue Type: Bug > Components: Tests > Affects Versions: 1.17.2 > Reporter: Sergey Nuyanzin > Priority: Critical > Labels: test-stability > > this build > https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=50816&view=logs&j=5c8e7682-d68f-54d1-16a2-a09310218a49&t=86f654fa-ab48-5c1a-25f4-7e7f6afb9bba&l=8056 > is failing > {noformat} > Jul 03 11:07:41 Finished > org.apache.flink.test.checkpointing.UnalignedCheckpointRescaleITCase#shouldRescaleUnalignedCheckpoint[upscale > keyed_different_parallelism from 7 to 12, sourceSleepMs = 0, > buffersPerChannel = 0]. > ##[error]Exit code 137 returned from process: file name '/bin/docker', > arguments 'exec -i -u 1004 -w /home/agent05_azpcontainer > 20ef21acb85dd401bac092e74118bbc65dae54ceb7e28fee9007fd15987f7d27 > /__a/externals/node/bin/node /__w/_temp/containerHandlerInvoker.js'. > Finishing: Test - tests > {noformat} -- This message was sent by Atlassian Jira (v8.20.10#820010)
