The English translation of that error message is "I was trying to query the
master to get the serial number of the XXX domain, but I got an error or
the connection timed out."

Often shortly after the first Err/TO log message there will be a log
message with a more specific explanation of the problem, like:

named-xfer[17696]: connect(4.23.73.56) for zone XXX failed: Connection timed out

The latter type of message will only show up once for the duration of the
problem, while the Err/TO messages will show up every time it tries to
query the master (after an error, this frequency is controlled by the Retry
setting in the zone's SOA record).
