  Start a listener on one node (both nodes running RHEL5.1/OFED1.3):

[root at poib01 ~]# nc -v -v -u -l 61984 | dd of=/dev/null bs=1024k

  Start a sender on another, which completes:

[root at poib04 mnt]# dd if=/dev/zero bs=1024k count=10000 | nc -v -v -u
36.102.28.91 61984
10000+0 records in
10000+0 records out
10485760000 bytes (10 GB) copied, 48.0578 seconds, 218 MB/s

  But the sender just hangs until ^C:

Connection from 36.102.28.94 port 61984 [udp/*] accepted
