This seems to be too much for ntp to compensate. Is it physical or virtual environment? If virtual, clock issues are common and, in case of VMWare, their tools handle them because ntp cannot. Still, never use a virtual machine as a time reference. If it's physical, my two cents are clueless. Maybe you wish to reduce the frequency of the clock; I know it's a kernel parameter, but don't remember which one. Best regards, Jil
