[^heap_dump_after_1_execution.zip] and [^heap_dump_after_10_executions.zip], in
case you can analyze it.

> Hi !
> Im running a 1.11.1 flink cluster, where I execute batch jobs made with
> DataSet API.
> I submit these jobs every day to calculate daily data.
> In every execution, cluster's used metaspace increase by 7MB and its never
> released.
> This ends up with an OutOfMemoryError caused by Metaspace every 15 days and i
> need to restart the cluster to clean the metaspace
> taskmanager.memory.jvm-metaspace.size is set to 512mb
> Any idea of what could be causing this metaspace grow and why is it not
> released ?
