Backup of dedup pool stalled

[David E Ehresman]

I am running a "backup stg ex-dsk ex-ofl maxpr=2" against a dedup FILE
storagepool.  One of the processes is stalled:

    655 Backup Storage Pool  Primary Pool EX-DSK, Copy Pool EX-OFL,
Files
                              Backed Up: 233013, Bytes Backed Up:
                              41,393,734,786, Unreadable Files: 0,
Unreadable
                              Bytes: 0. Current Physical File (bytes):
None
                              Current input volume:
/tsm/dedup/V386633623.BFS.
                              Current output volume(s): 100766JA.

There is no Current Physical File and the number of Files Backed Up is
not increasing.  The 2nd process is continue to backup data.  Any ideas
why this process might be stalled instead of ending?
