-----------------------------------------
Summary: Logging warning of insufficient memory for all configured
buffers
Key: FLINK-25590
URL: https://issues.apache.org/jira/browse/FLINK-25590
Project: Flink
Issue Type: Improvement
Components: Runtime / Network
Affects Versions: 1.15.0
Reporter: Anton Kalashnikov
Right now, if exclusive buffers for the input channel and one buffer for each
subpartition would be allocated on start successfully but there would be not
enough memory for the rest of the buffers(floating buffers, rest buffers for
subpartitions), then we see nothing in the log about that(as I understand).
So first of all, we need to check what logs we have right now about situations
when flink doesn't have enough memory for all configured buffers. And if we
have nothing (or not enough) we should add such a log.
