[Openib-windows] SM errors

[Jeremy Enos]

We're having intermittent failures of IPoIB on a 420 node windows 
cluster.  In the osm.log, I find several lines like this:

[17:28:59:810][0954] -> __osm_al_send_callback: ERR 3b0b request mad had 
failed.

[17:28:59:841][0954] -> __osm_al_send_callback: ERR 3b0b request mad had

1)  What does this mean?
2)  Is there a place I can look up errors before posting to this list?
thx-
