Andrey Zagrebin commented on FLINK-18153:
-----------------------------------------
We could indeed check the size against reasonable limits depending on JVM
bit-ness.
> flink-daemon does not detect errors if JVM crashes immediately

> Key: FLINK-18153
> URL: https://issues.apache.org/jira/browse/FLINK-18153
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.11.0
> Reporter: Chesnay Schepler
> Priority: Major
>
> Configuring obscenely large amounts of memory that exceed the machine, which
> prevents the JMV startup, does not result in any error to be printed to the
> console. The logs are empty, and the only hint for an error is found in the
> .out file.
> {code}
> OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x00007aaf70000000,
> 5241403604992, 0) failed; error='Not enough space' (errno=12)
> #
> # There is insufficient memory for the Java Runtime Environment to continue.
> # Native memory allocation (mmap) failed to map 5241403604992 bytes for
> committing reserved memory.
> {code}
> This behavior is just a bit too subtle.
