After rolling back from a remote backup, I enabled again my usual daily replication to my remote backup. One dataset starts but seems frozen. All the other replicated datasets without any issue. The web GUI replication page does not allow to see any log or progression when clicked on "RUNNING".
TrueNAS web GUI issued the following general notification:
The following system core files were found: zfs.core. Please create a ticket at https://jira.ixsystems.com/ and attach the relevant core files along with a system debug. Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores
This has already been fixed in newer versions of TrueNAS.

please inspect zfs.core, in case there is something interesting there

After a reboot and letting it run again, it seemed to have worked, without changes the settings. Note that the web UI complained about not having "an incremental basis to start from", which seems odd, since the replication is configured to keep snapshots in synchronization, even it means starting from scratch.
So, problem solved, but maybe something to look out for.

Maybe an important note, before it came to this, under the "Replication Tasks" tab, I could see that this specific dataset replication was running. When clicking on "RUNNING", the progression was stuck at "0.00%". Meanwhile, I can see trafic on NICs on both the local and the remote machines.
