    The messages on IP addresses were just warnings, in the first case, the DNS lookup couldn't resolve the ip, in the second case, the host name looks like an IP address. Neither of these warnings would cause mysqld to shutdown.

    There is no error message around the timestamp of this restart. Either something was seriously wrong and mysqld didn't get a chance to leave any hint, or the mysqld process was killed abruptly.

    Can you please check error log for each restart and see if there was always no error logged before each restart? And please check if there could be any chance that some process kills mysqld.
