[Bug 535583] Re: Excessive logging by apcsmart program
Of course after a reboot, I forgot to stop nut and start apcsmart
with debugging. :-( So when the problem reoccurred, I didn't get the
debug output.
But I ran strace of the apcsmart process, you might be able to
use that instead.
write(4, Y, 1)= -1 EIO (Input/output error)

I have no idea why there is an IO error on the serial port. When I
restart apcsmart, it works OK. But it does not seem to handle the
EIO, it just goes on and on looking for input on /dev/ttyS2 and
/var/run/nut/apcsmart-ups (on two FDs), but then ignores the input
available on /dev/ttyS2.
The 'Y' command tells the UPS to enter smart mode. I can imagine this
is the normal mode of operation, and apcsmart has been thrown off track
and tries to re-engage, but the code that is supposed to do this is
faulty. Or maybe the UPS has dropped the connection. When I unplug the
cable, the trace is similar but different:
