UPS is lost at the random point

[Meldo]

Binary package hint: nut

Ups in nut works nice, but only for some time.
It is something from 30m to 4h. After aforementioned time passed ups is lost.
BUT ups can be easily regained: root need to restart nut.
While it is a workaround, but still not desirable behavior.

Expected: UPS never lost while it is connected to box.

Arnaud,

Do you have any comments?

What additional information required?

It seems i got the pattern. UPS is lost only if nut started at system start up.
If nut restarted manually, it seems to be never lost, or at least i yet to see lost UPS event after manual restart.
Also, it seems, 4h is not an upper limit. It can work stable for day and then become lost.
