Look like the SQL/Slammer worm. It targets UDP port 1434 (MS-SQL servers
listen there), consists of single packets that are 376 byte in size and causes
Seems like the machine at 184.108.40.206 is infected, so not much you can do
to stop this packet flood. May try to contact the server admin and convince
him to reboot and patch the MS-SQL server. Or ask your provider to block
incoming packets on this port for your server.
