    backup.c:666 Network send error to SD. ERR=An existing connection was forcibly closed by the remote host.

    Error description

    This can happen when the Storage Daemon shuts down due to being killed by a process, which looks for out-of-space issues. It can also be due to a network connectivity problem, in which the TCP stack on the appliance eventually closes the connection with a RESET.
