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).
