backup mail report says INTERRUPTED but it's not ?

Pilow

we have a strange behavior in the mail reports of XOA Backup.

the backup is done, we see the delta point on the remote, in XOA it's all green, no sign of INTERRUPTED, but the mail report tells otherwise :

the "INTERRUPTION" seems to happen on the remote

the point in the remote :
in XOA logs :

other backups are okay, this same one will be okay too tonight...

what is happening ?
false alarm ? @florent @bastien-nollet

some timeout or race condition between the end of the job and the mail generation ?

perhaps putting 10sec delay to send mail ?
