Matthias Pohl commented on FLINK-32533: --------------------------------------- This issue might be a duplicate to FLINK-18356. See my comment in FLINK-32532 for the reason. The build failure happened around the same time: {quote}The failure you describe happened on agent AlibabaCI005-agent01 on Jul 03 at 15:33:45. 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 AlibabaCI005-agent04 (i.e. same VM) on Jul 3 at 15:32:38. 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). {quote} > exit code 137 (i.e. OutOfMemoryError) in python module > ------------------------------------------------------ > > Key: FLINK-32533 > URL: https://issues.apache.org/jira/browse/FLINK-32533 > Project: Flink > Issue Type: Bug > Components: API / Python > 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=50839&view=logs&j=9cada3cb-c1d3-5621-16da-0f718fb86602&t=c67e71ed-6451-5d26-8920-5a8cf9651901&l=24053 > is failing like > {noformat} > Jul 03 15:31:56 pyflink/datastream/tests/test_data_stream.py > ...........................
