Thomas Weise commented on BEAM-5167:
------------------------------------

The issue can be reproduced by running wordcount in *batch mode* with embedded 
Flink with --parallelism=8 --experiments=worker_threads=8 

Changing to --parallelism=8 --experiments=worker_threads=12 allows the pipeline 
to complete.  

Streaming mode does not exhibit the same problem.
