Not shure. I can't find way for collect output of UMA_DEBUG* with current console server and it can't be replaced before Jan. But I think UMA* is a wrong idea. You suppose bad hardware (I'm right?). Possible. But it can be detected only under heavy load -- when I enabling nagios on this server. When nagios disabled, machine work perfectly. With enabled UMA_DEBUG* options server not operable, no one service starting, we don't have this load and can't reproduce this behaviour. WBR Dmitriy
