Jeff Klukas commented on BEAM-12356:
------------------------------------
I also have just observed a recurrence of this issue in a Dataflow pipeline
running Java SDK 2.31.0. We had previously downgraded to 2.28.0 waiting for
this fix. It looks to be less frequent than it was on 2.29.0, but is still
happening.
> BigQueryWriteClient in DatasetServiceImpl is not closed, which causes
> "ManagedChannel allocation site" exceptions
