ParallelConsumer would run for a while and then exit due to InternalRuntimeException(Timeout)

Hi team,
version 0.5.3.1

**InternalRuntimeException:**
My test scenario is a scenario where 50% of records fail, and there's 1000 keys in total, parallelConsumer would run for a while and then exit due to InternalRuntimeException at 24/09/13 21:33:37.130
io.confluent.parallelconsumer.internal.InternalRuntimeException: Timeout waiting for commit response PT30S to request ConsumerOffsetCommitter.CommitRequest(id=79c3ac04-b8c7-4dc2-9b09-c77d6ad6bee4, requestedAtMs=1726234432425)

And we can see the code from ConsumerOffsetCommitter.commitAndWait()

` CommitResponse take = commitResponseQueue.poll(commitTimeout.toMillis(), TimeUnit.MILLISECONDS); // blocks, drain until we find our response
`
cause take is null then throw InternalRuntimeException.

**metrics from pc_processed_records_total**
During this time, there's no successful records:

**Adding commit response to queue:**
And below logs from ConsumerOffsetCommitter.maybeDoCommit() show the last time add commit response to queue is 24/09/13 21:16:54.105

**Waiting on a commit response:**

And we can see the code from ConsumerOffsetCommitter.commitAndWait() show the last time wait commit response from queue is 24/09/13 21:33:52.426

Here's my concerns:
First time adding commit response to queue time is 24/09/13 21:16:54.105, and waiting on a commit response time is 24/09/13 21:16:54.084, within 30s
second time there's no adding commit response to queue but waiting on a commit response time is 24/09/13 21:33:39.194.
so it lead to InternalRuntimeException.

please help to check

Start with ConsumerOffsetCommitter.commitAndWait() and maybeDoCommit(), using the reported 0.5.3.1 scenario with 50% failing records and 1,000 keys. Trace why a commit response is not added to the queue before the 30-second poll timeout. Done means the failure cause is identified and the consumer no longer exits unexpectedly in this scenario.
