[ https://issues.apache.org/jira/browse/FLINK-26177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18129199#comment-18129199 ]
Martijn Visser commented on FLINK-26177:
----------------------------------------
Another occurrence, weekly 2026-10-11 on v4.2 (Flink 1.20.4), this time on JDK 11. PulsarSourceE2ECase.testScaleDown hung in restartFromSavepoint until the step timeout, same main thread as above:
https://github.com/apache/flink-connector-pulsar/actions/runs/38100217710/job/114354436179
The 2026-10-18 weekly and the push and PR runs since 2026-10-06 passed it.
