[openib-general] [openfabrics-ewg] problems running MVAPICH on OFED 1.1 rc6 with SLES10 x86_64

[Scott Weitzenkamp (sweitzen)]

Aha, I found something in /etc/hosts, thanks for the hint.

	127.0.0.2       svbu-qa1850-3.cisco.com svbu-qa1850-3

If I comment this line out, MVAPICH works fine.  Does Mellanox have this
entry in /etc/hosts?
