Script crashing

After upgrading my BrewPi Spark, it has been crashign regularly. Here are some log files:

#2

Just checked the upgrade. Seems it failed when trying to stash a config.example file. I ran the update again and selected N when asked to stash the file. Will check again later to see if the BrewPi is stable.

I’m still having problems with the script crashing regularly. Here is more log information:

Is it possible to get support for this problem? For a week now the BrewPi Spark has been continuously disconnecting. I’ve tried through the forums and by selecting Contact Us from the store, no response from either.


#6

Hi, sorry for the late reply. Here are some things to check:

  • Are you running the latest version of the docker container?
  • What is the IP address shown on the display of the Spark?
  • What is the state of the LED on the Spark?

Is the Spark far away from your router?


#7

I am not sure how to check the version of the docker container. I’m new to using docker. I went through the update steps about a week ago, both the script and firmware were updated. That is when the connection problems started. From the end of December 2017 to last week the BrewPi spark was very stable.

The ip address is 192.168.1.99

The LED is light blue very slowly blinking
The spark is a few inches from the RaspberryPi that is reading the information. It is about 15 feet from the router. There is also 2 ip cameras and a tilt int he same room that dont have connection problems, and an extender a few feet away.

Thanks for your help.


#8

If the LED is slowly breathing cyan, the spark as a good connection.
If you say you updated the script manually, you are probably not using docker are you?

Do you have portainer running on he pi? You can recreate an existing container with the latest image from the portainer web interface.


#9

I am using portainer. I updated in the console in portainer by running ~/brewpi-tools/python updater.py


#10

We release a new docker container that contains the latest version of the code each time the code updates.
Your settings are persisted outside of the container.

The best approach to update is therefore to get the latest version of the container, instead of running an update inside an existing container.
The easiest way to update the container is let portainer re-create it. Browse to the BrewPi container and click ‘recreate’. Leave ‘pull latest image’ ticked.


#11

Ok, updated using that method. I’ll let you know if there are any more connection problems.


#12

This helped me out as well and the spark connected immediately with the new brewpi container.
