I discovered today that weewx was no longer running. It had been running
fine for several days. I installed it late last week using the Debian
instructions <http://weewx.com/docs/debian.htm> and used these instructions
<http://landoflinux.com/linux_raspberry_pi_weather_station.html> regarding
installation of the HP1000 driver. At the bottom of this post I included
the crash related entries +/- a few lines as well as what I see in
systemctl. I'm not sure but possibly the HP1000 driver got a malformed
packet from my AW WS-1001 (?). As far as I can tell there was no effort by
the system to restart weewx. I did confirm there was no weewx process
running.
Do you have any advice on how to have it better cope with this error? If it
happened once after a few days I imagine it will happen again. There were
no known networking issues yesterday. Thanks!
I did a systemctl status command and weewx was listed there as expected:
