This is really weird. There are basically two ways for upsd (by means of the sstate_dead() function) to determine the *driver* is stale (it has nothing to do with the UPS, we'd better change the wording of the error messages). Either the driver has not send us anything within MAXAGE seconds or upsd has problems maintaining the connection to the driver socket. Unless you've changed the value of MAXAGE to some ludicrous low value of two seconds, this might be a socket problem. I recall someone having similar problems on a *BSD system a while ago. What system are you using? Could you check if the socket is in /var/state/ups? Whatever happens, the driver should *not* remove the socket if it can't communicate with the UPS. It should call dstate_datastale() rather than giving up the socket in that case (this is not how the line of communication works). So the problem is probably in the driver, since it has no problems keeping the socket fresh when the UPS is connected.

You can do this by means of a script that is called by NOTIFYCMD (see 'man 5 upsmon.conf') or through upssched (see 'man 8 upssched'), which is more flexible.

[Nut-upsuser] "no longer stale" when disconnected with 2.0.5 newhidups
Hello, I'm using driver newhidups with APC Back-UPS CS 500. Most things works fine except the following: After I disconnect the UPS the upsd write "Data for UPS [apc] is stale - check driver" in /var/log/messages. In the same second it tells "UPS [apc] data is no longer stale". This repeats all the time the ups is disconnected: Jan 25 14:45:03 degpn026w226 kernel: usb 4-1: USB disconnect, address 3 Jan 25 14:45:06 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:08 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:10 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:10 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:12 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:12 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:14 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:14 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:16 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:16 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:18 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:18 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale Jan 25 14:45:20 degpn026w226 upsd[4275]: Data for UPS [apc] is stale - check driver Jan 25 14:45:20 degpn026w226 upsd[4275]: UPS [apc] data is no longer stale After reconnect the ups, the communication is ok and nut works until I disconnect again.
