    MpxTestDaemon chewing up cpu ... what is this process?

    john hurley
      I have 5 boxes running OL 6.2 64 bit using redhat compatible kernel ... working on a migration to 11.2 database ...

      6574 root 20 0 0 0 0 D 15.6 0.0 496:33.72 MpxTestDaemon

      One of my boxes since the last reboot has this process chewing up cpu ... never seen this before ... any and all ideas appreciated.

      There seem to be two MpxTestDaemons running one is no cpu ...
