Well, then there seems to be a problem with rcd_serial.
According to the exit code (142 = 128 + 14), it seems like the
plugin instance gets killed by the ALRM signal. The signal
should've been caught, but there is something wrong with the
registration of the signal handler.

Looks like this fails unexpectedly:

#if !defined(HAVE_POSIX_SIGNALS)

because our autoconf doesn't do tests for signal implementation.

Can you please try the attached patch? You'll have to rebuild
the package for that.

Thanks,

Dejan
