New description:

 I am running a dedicated mythbackend with 4 PVR-150 cards.  I am seeing a
 repeated crashes of the backend after running for several days.  It
 appears that the series of events leading up to the event is that at least
 1 PVR-150 card becomes unavailable for a period of time, then a recording
 finished, then scheduling starts, then a malloc memory corruption error is
 generated.

 I am attaching the mythbackend.log with the events leading up to the crash
 and the crash dump itself.  The crash occurs about 1/2 way through the log
 at "2011-03-28 23:01:00.737"
