Martijn Visser commented on FLINK-38501:
----------------------------------------
This is not confined to {{test_cron_azure core}}. In the eight days 2026-09-09
to 2026-09-16 the
same fork-start failure hit 14 runs on all four maintained branches, on both
Azure and GitHub
Actions, on JDK 8, 11, 17 and 21, and under the default, AdaptiveScheduler and
Hadoop 3.1.3
profiles. Ten were nightlies (10 of the 52 nightlies in that window) and four
were push runs.

[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:3.2.2:test (default-test) on
project flink-runtime:
[ERROR] ExecutionException The forked VM terminated without properly saying
goodbye. VM crash or System.exit called?
[ERROR] Error occurred in starting fork, check output in log
[ERROR] Process Exit Code: 239
[ERROR] Crashed tests:
[ERROR] org.apache.flink.runtime.memory.MemoryManagerConcurrentModReleaseTest
{code}
The class under "Crashed tests" is different every time -- WorkerCounterTest,
ConnectionUtilsTest,
ResourceManagerJobMasterTest, BlobClientTest, SSLUtilsTest,
ResourceManagerHATest,
MemoryManagerConcurrentModReleaseTest -- and the fork never produced any test
output, so it is the
fork that fails to start rather than any of those suites.
