Interrupt latency problems (lost clock interrupts) are about the only thing that will cause this. The other Windows problems (multi-media timers and scheduling uncertainties) will result in unstable but bounded errors. Multi-media timers may still be an issue, because, by using shorter ticks, they increase the chance of exceeding the clock latency limits, but the only solution is to not use them at all. More likely problems in this case are, depending on what this package does, are that it contains device driver code with unacceptably long periods of disabled interrupts, or that it is very aggressive in its use of a device driver which disables for excessive periods - typically disk drivers. It's just possible that this software attempts to discipline the clock itself. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
