[Bug]: Dataflow job stuckness related to big query storage api

Hi team,

My team has a dataflow job using python sdk that writes pubsub messages to multiple big query tables (inside the pipeline it will also create table using bigquery client if destinating table does not exist). Currently we have increasing among of times where the job got stuck with this error message: `operation ongoing for over 189595.35 seconds in state process-msecs in step Stream to BigQuery-ptransform-23 without returning`.

Error logs:

What is the possible reason for this?
