[ADSM-L] TSM 6.1.3.3 migration processes appear to idle

This is one of those "anybody seen this?" questions.

This TSM server is unfortunately plagued with several clients that send
humongous files.

 

Migration is sometimes trigged by disk pool full, sometimes does not
occur until maintenance script starts migration by command.

3 migration processes run concurrently.

What I notice often is the situation as shown below.

One or two of the migration processes are busy chewing on these really
large files, and the others appear to be idle.

 

The apparently idle session (in this case 113) will sit for long periods
(sometimes hours) with:

-         q proc showing "current physical file: NONE"

-        no increase in files/bytes moved

-        and q session shows no backup sessions in progress, either

 

I'm naturally wondering why it's sitting there.

 

Does anybody else see this behavior in any release of the server?

Anybody know if this is WAD?  

 

I would certainly prefer the extra session to terminate and release the
drive.

 

Thx
