Hi,
Flink uses a few libraries that allocate direct (off-heap) memory (Netty,
RocksDB). Flink can also allocate direct memory by itself (only relevant
for batch setups though).
Therefore, Xmx controls only one part of Flink's memory footprint.

Hi, Szczypiński
Do you have noticed the size of the maxDirectMemorySize in your taskamanger
jvm options， AFAIK the total memory one Taskmanager used is the (heap memory
+ directMemory) which may larger than the heap size specified by -Xmx?
Best wishes
