  Full memory map could be found in attached 'messages' log.
  When rsyslog crashes in this manner it is impossible to login into the system. Process /bin/login successfully authenticates user, but does not born shell process, constantly waiting for rsyslog reading login log message from Unix socket.

  Obviously Fuel master reports that node in 'False' state (because it
  becomes non-sshable too).

  Workaround: fully restart rsyslog after crash (service rsyslog
  restart) if some active login session is present or reboot the server
  if not.

  MOS 6.0, Ubuntu 12.04. Rsyslog v. 5.8.6 (from Fuel node repos).
  Rsyslog config files placed in rsyslog folder of attached archive.
