<P><FONT size=2><FONT face=Arial>Hi ,<BR>I'm working on the SM group at
Mellanox.<BR>While testing SM-gen2 on a loopback , I've encountered a basic
problem trying to send an SA query (single mad) over osm_vendor
(gen2).<BR>Trying to send the request using osm_vendor_send , passed succesfully
, BUT got from the receiver (umad_recv) an error (in an endless loop ):
"No space left on device". The MAD request was simple GSI - SA request of
ClassPortInfo , here are the details , I've truned on debug mode of vendor_lib
and umad (marked in red the important lines in the log ):<BR>...<BR>Aug 02
