Crash after a few days of running

[nohn]

I'm running sml2mqtt on a Raspi 2. This night, it crashed:

syslog doesn't contain anything interesting.

[spacemanspiff2007]

I've added a frame dump when an error occurs. Could you update to the latest version and observe the logs and report back with the frame please?

[nohn]

Sure, I'll do. Will you push it to PyPI?

[spacemanspiff2007]

Hm - I'll check the mqtt issue first. Maybe I can include the reconnect in the new version, too. Would it be possible that you replace the sources in site-packages?

[nohn]

Done.

Apparently the workaround in #3 does not work. Only explanation I have is that in case of this exception, the application exits with return code 0. Could that be possible?

[spacemanspiff2007]

I've made an update which should fix the mqtt reconnect issue and reworked some of the shutdown logic. The app should now properly exit with != 0 on error. Could you try again?

[nohn]

I've updated the code and give feedback in a few days.

[spacemanspiff2007]

Thank you. The Application should shut properly shut down on error and log the return code.

[nohn]

Proper shut down works now, so systemd can restart the service:

Thank you for reporting back!

[mrumpf]

I have another error every few hours which stops sml2mqtt from reporting any values. It does seem that the Python process does not exit and thus systemd not restarting the service:

[spacemanspiff2007]

I just fixed an issue in the smllib but I have not yet ported it back to the sml2mqtt application. Would you mind sharing the frame (redact your personal information) just so I can make sure this is not another issue?

Nonetheless the application should exit properly ...

[mrumpf]

Will the frame be dumped with debug logging turned on or how can I get hold of the frame that causes the issue?

[spacemanspiff2007]

Yes - it should be right above the Traceback you posted

[mrumpf]

Hm, there is nothing in the log. Here is the log with some more context:

So the tool logs show PORT_OPENED & OK and then a few hours later the traceback gets dumped without any further information.

Wouldn't it be possible to just skip the current frame and continue with the next one instead of stopping the execution completely in case of a parsing error?

I've already fixed the issue in the underlying library but I have yet to port the changes to sml2mqtt. Maybe over the course of next week I'll find the time to do it.

[mrumpf]

Great. Thank you! The log somehow indicates that the port is opened again after it was closed but no data is read anymore. When I restart the service with "systemctl restart sml2mqtt" it works again. So I see 2 issues, one is the parsing error which raises an exception and the second one is that reopening the port does not work anymore. Unfortunately I have no idea why the serial port read does not return data anymore.

[spacemanspiff2007]

@mrumpf Do you still experience the issue?

[steigerbalett]

@spacemanspiff2007: The issue is still present in my system. I have to restart sml2mqtt continuous

[spacemanspiff2007]

Which version are you running and can you post the logfile please?

[steigerbalett]

Logfile is 104 MB :-D Most is like:

But I recogniced, that i am still on Version 1.0.1 - so I have to update and reverify the problem: [2022-06-02 08:34:37,316] [sml ] INFO | Starting V1.0.1

I updated and will monitor it with the new version: [2022-06-03 20:20:39,178] [sml ] INFO | Starting V1.1.0 [2022-06-03 20:20:39,292] [sml.ttyUSB0.status ] INFO | PORT_OPENED [2022-06-03 20:20:39,979] [sml.ttyUSB0.status ] INFO | OK

The Problem still exist in my setup (see attached logfile snippet):

Could you try again with 1.2.0? I added a fallback there.

[steigerbalett]

Still up and running 👍

As you can see in the log the fallback is working. If you experience any more issues feel free to open another issue.
