So it is per-client-process (or per-client-connection) not quite per-client-host which seems to confirm that it is not a straight networking issue that suddenly emerged (again clients and servers in these tests are connected to the same switch). _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
