<BR>
<P><FONT SIZE=2> I missed the following lines when I did cut and paste of the code -<BR>
elem -> u.txwr.opcode = IB_WR_SEND;<BR>
elem -> u.txwr.next = NULL; /* Send only one */<BR>
<BR>
So it is not the obvious error, it may be something else.<BR>
<BR>
(Yes, I need to correct the coding style errors.)<BR>

It's a little hard to debug without being able to run your code and<BR>
reproduce the error. The only things I see obviously wrong are that<BR>
you never seem to set elem -> u.txwr.opcode to IB_WR_SEND, so you may<BR>
be posting an invalid work request, and also you never set elem -><BR>
u.txwr.next to NULL, so ib_post_send() could follow the next pointer<BR>
into some other memory and post a random work request.<BR>
<BR>
(BTW, if your coding style is to put spaces around every operator,<BR>
shouldn't you write things like 'elem -> u . txwr . next'? ;)<BR>
