These failures are from rdma_cm_bind indicating the port is already 
bound to this IA address. How are you creating the service point?
dat_psp_create or dat_psp_create_any? If it is psp_create_any then you 
will see some failures until it  gets to a free port. That is normal. 
Just make sure your create call returns DAT_SUCCESS.

This is a real problem with the bind, port is already in use. Not sure 
why this would fail since the current version of OFED uDAPL uses a 
wildcard port when binding and uses the address from the open;  I 
remember an issue a while back with rdma_cm and wildcard ports. What 
version of OFED are you using?
