Comment(by cwsmith ):

 here is a copy of my servers backend log before it started to happening i
 have been in mythtv-users channel and some suggestions were that ext3 was
 cauing an i/o problem so i went to an XFS filesystem also suggested that
 mysqld binary logging was enabled its not enabled on this box, also that
 dma was not enabled it is enabled. and this has happened again :(

 below is a copy of my mythbackend.log file just before it has happened

 also its important to know that once these errors start happening i get
 642 pages plug until the backend is restarted before they quit thanks
