> A Flink user who's running Flink on YARN with 1 processing slot, 2 GB of TM memory on a machine with 48 reported CPU cores is running into issues with TM containers being killed due to memory overuse.
> Setting the YARN memory cutoff to 0.5 resolves the problem, but its not really a feasible approach.
> Another solution to the problem was downgrading netty again from 4.0.31.Final to 4.0.27.Final resolved the issue.
> We upgraded Netty between 0.9 and 0.10.
> Most likely netty changed its behavior between the releases.
