Img burn has frozen while writing a blu ray disk

[ss06470]

I erased as suggested a Verbatim BD-RE DL.  Then began burning a file from my hard drive to the disc  using an Samsung SE 506 BB  Everything was going along  fine until it was 58% finished.  The last message on the log was Writing layer 1  (LBA12219392-22165375)  There are no  yellow error messages but the write rate is 0 KB.  Time remaining is unknown, size and time are not throwing out new numbers.  There are no write retries.  The only thing changing is time elapsed.  It has been like this for at least 45 minutes

Post the log please - just copy + paste everything from the Log window.

 

It only ever waits for your system to process a command. If it stops processing them, ImgBurn just sits there waiting.
