Hi Bernd,

we are also using 1.3.1 and Lustre, as you have seen recently at our
site ;-)

I'm getting messages like these only when large computing jobs are
running using IPoIB. I believe that this is a issue with send/receive
buffers, because I see dropped packets on IPoIB iface. Those jobs work
usually fine (usually because this app is buggy itself) so I find
those messages rather harmless.

regards, P
