I have had similar experiences with 5.x on Windows clients.  

It turned out to be VSP causing the jobs to hang.  After I disabled VSP on 
the problematic clients, the jobs didn't hang and finished with status 
code "1".

To disable VSP:

1.  from master server, use the bpclient command.  bpclient -help for all the 
options.

I hope this helps you all.
