We had this problem with 6.5. With previous NBU versions we had only  the
make_scsi_dev problem
We Change from Linux to Solaris x86_64 before one month and now I remember
Linux media servers only as a bad (bad bad...) dream.

Hi,

Same here... but it has happened twice a year only.. and the solution is
only to restart the Redhat 4 server.
Once restarted the server it is back to normal.

With Warm Regards
