### What happened?
I have a pipeline running on Dataflow which pulls messages from PubSub and
then writes to Bigtable via `BigtableIO`. We see many instances of logs such as
the following:
```

```
Eventually the service gets completely stuck and quits writing anything to
BT, though it never stops pulling and acknowledging messages from the
subscription. I've observed this behavior in versions 2.48.0 and 2.50.0, though
not in 2.33.0 (which is what we were using prior to upgrading recently). We're
using Scala with Scio (at the respective versions for each Beam version we've
tried).
