FIle Not Importing

Hi,

Have a strange problem where two files were copied into a watched folder and only one got imported. 

Directory listing:
-rw-rw---- 1 www-data www-data 4319616 2012-05-03 09:32 4-5min-03-05-2012.mp3
-rw-rw---- 1 www-data www-data 4319616 2012-05-07 09:15 MNN_4-5min-07-05-2012.mp3   <--- Did not import as process had died.

Log
attached but ends on May 03.  It appears there was an exception.  So
I'm guessing the process needs to be restarted but didn't want to do
that until the cause was sorted out.

Any ideas?  Does the attached log and errors about not reading a byte at position... give any clues?
