Hi! In order to answer this, we need a bit more information. Here are some followup questions:
- Did you submit any job to the cluster, or is the memory just growing even on an idle TaskManager? - If you are running a job, do you use the RocksDB state backend, of the FileSystem state backend? - Does it grow infinitely, or simply up a certain point and then goes down again?
