Okay, done that. The output is at

Ive set pan to get headers for a.b.image group or something. During the 
stals I fired strace for a few secs.

First three files were started during a stall en stoped before it 
continued. The fourth was while running happily and during the fifth it 
was running wel and bumped into a stall.

Btw, thanks guys for the help sofar.
