We installed RedHat Linux (kernel 2.4.7-10smp) on an TC4100 with two Prozssors 1.4 GHz. After one week the "date" time stops and the server hangs. The hwclock runs normal. After hard reboot the "date" time runs normal. In two ather installations with the same configuration, we have also this problem. Every monday morning the "date" time goes slow or stops.At this time run no scripts on the machine.
You should update the machines as a first step. I know that 2.4.9-34 is the current recommended kernel for redhat 7.2 (which looks like what you're running).
