HI,
Previously we had -1 as default for both of these instances and that caused same kind of issue.
Now we had set it to maximum value. We changed it back to -1
The logical replication was rebuilt over the weekend from scratch and issue occurred only 2-3 days after.
So we believe this is a bug. There seems to have been an issue in 13, that got fixed. But maybe this is a regression bug?

Aihe: Re:Logical replication halted due to "this slot has been invalidated because it exceeded the maximum reserved size."
Hello
> The only explanation of this behavior that doesn't involve a bug is that
this parameter was set to a nonzero value, then set to disabled, but the
checkpointer failed to notice the change.
Or max_slot_wal_keep_size is really set on the publication database, but only the subscription database config was checked.
