Hi, I have a Linux Cluster, which runs "well". But I still have problem with License Server. Sometimes I get a message "License Server Connection Lost" And the calculations are freezed. Someone told me that it could happened if the host machine on which is the license server is overloaded. But I still have the problem with small grids. When I spawn my nodes, I become always a Warning :" Multiple Networks Configured on the system. Ensure optimal choice of network interface and fluent communication". I Have 3 networks services: rlogin / rexec / rsh Do I have to disable rlogin and rexec? THanks Maxime

(a) check if exists interfaces down/up messages into the system messages file ? (b) when the license manager is reloaded, some applications loses the connection. but i do not know if it would be the case.
