URL: https://github.com/apache/iceberg/issues/13752
### Apache Iceberg version
1.9.2 (latest release)
### Query engine
Trino
### Please describe the bug 🐞
I have running instance in k8s that is putting Kafka's messages to my
Iceberg tables. From time to time, after the restart I have the following, as I
suppose Glue-related, issues in logs, preceded by some commit related warning:
```

sometimes, before timeout, I see the following messages for the commit:
```

ready, received responses for 1 of 3 partitions, waiting for more
```
This is definitely some issue I should take a look into, but what is
worrying me most is the fact that Kafka Connect is loosing data - it's not in
Iceberg anymore and never appear there. The problems I described above usually
are being solved with the next restart of my instance but the data is never
reprocessed
I've checked source topic offsets and they're just getting bigger, probably
never reverts. I've checked my configuration and I see that `errors.tolerance`
is not overwritten so I suppose it should be `none` but all workers are in
`RUNNING` state
I've checked control topic `connect-offsets` but it is empty - I did read
somewhere that it's expected because it's not being used for Sinks.
Did anyone had this issue?
