The upsmon "data stale" error is a symptom of the driver not starting. Is there any other information in the event log about why the driver did not start?

Also, when you say "one or two days in a week", is the driver failing during that time, or is the computer restarted that often?

None of our releases are labeled "last port" :-) What is the version number?

Also, if you have a Linux system that can talk to the UPS, that is probably a more reliable solution. At the very least, it is easier to get debugging information out of the driver.

As mentioned earlier, the blazer driver has been replaced with the nutdrv_qx driver, but as you may have seen, that is not in the Windows port of NUT yet. If you know of any Windows (mingw) developers who are interested, we would appreciate their help.
