Interesting. I'll try to look at this next week - shouldnt be too hard to debug if I manage to reproduce it here. Meanwhile, could you please try to enable sdp data debugging, and post the resulting log if the problem reproduces there? -- MST _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
