occ's user:info says 'user not found' on stdout with an empty stderr, so the
error read as 'occ produced no output' and mesh-admin was never made on novox:
occ now says stderr and stdout both, and existence is read from user:list.
The repair could reset whatever account the user setting names, the
operator's included, and the 'admin' fallback is a hand-made install's human
administrator: only mesh-admin is repaired now, and it is the default. The
shares poll needs no admin rights, so the account gets no group. After a
repair the throttle of the caller's address is reset, and a failing repair
reaches the back-off's one loud line with occ's message.
