We can replay the problem: we load a table of several Gb in the schema of the publisher, this generates the worker's timeout after one minute from the end of this load. The table on which this load is executed is not replicated.

Before increasing value for wal_sender_timeout and wal_receiver_timeout I thought to further investigate the mechanisms leading to this timeout.

Okay, but there is no log corresponding to operations being performed by the publisher. By looking at current logs it is not very clear to me what might have caused this. Did you try increasing wal_sender_timeout and wal_receiver_timeout?
