Occasionally I experience short freezes - that is the machine stops to respond for a few seconds and then happily starts to work again. My general question is what log should I inspect or what debugging to turn on to have some more info on what really happens? It does seem to happen under bigger load (something like over 1) but I am not really sure if that is the cause. Yesterday it ran for three hours with an average load of over 2 and there was no freeze. Many thanks in advance for guiding me in troubleshooting the issue. -- Zbigniew Szalbot
