The appropriate fix has been merged on the downstream OSP13 patches branch, which was identified via additional logging information supplied by the customer, which was different from the originally requested patches to be backported as the operating configuration is different.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
