Event ID: 2019 The server was unable to allocate from the system nonpaged pool because the pool was empty

One of my domain controller stop functioning every 2-3 days. No users can logon to the server not even to say the file service. I realised this is caused by one of my HP printer that uses the HP Standard TCP/IP Port Monitor uses a host name in the port configuration.
