IPoIB CM HA failover and eventual failing IPoIB HA<BR></FONT><BR></DIV>

<DIV><SPAN class=497035801-02052007><FONT face=Arial size=2>With IPoIB HA (both
ipoibtools and ib-bonding), I am seeing slow IPoIB CM HA failover, and
eventually IPoIB stops working after enough failovers. I am running
netperf -D traffic between two IPoIB HA hosts, while flipping the 4 host IB
ports one at a time (port 1 down, sleep, port 1 up, sleep, ..., port 4 down,
sleep, port 4 up, sleep) in a loop.</FONT></SPAN></DIV>

<DIV><SPAN class=497035801-02052007><FONT face=Arial size=2>This is a very easy
test to set up. Can Mellanox and Voltaire please try to reproduce the
problem?</FONT></SPAN></DIV>

<DIV><SPAN class=497035801-02052007><FONT face=Arial size=2>I think this problem
must be fixed for OFED 1.2 rc3.</FONT></SPAN></DIV>
