pima.service hangs indefinitely after few days of running #9

Open maorcc opened 3 years ago

Every few days I need to restart the pima.service when it stops functioning. Here is what I see in the log:

It looks like the process is blocked waiting on a mutex. Here is the output of strace:

pi@raspberrypi:~/pima $ sudo strace -p 368
strace: Process 368 attached

@maorcc I see you are using Dror's tool. I was wondering if you using it directly via a serial connection, or you bought the home automation kit from PIMA ? I've just tried it with the serial connection and can't get it to work for the moment. Which version of PIMA do you have ? I'm at HP896

maorcc commented 3 years ago

@Jens-Wymeersch , yes I use Dror's tool directly via a serial connection from a Raspberry PI Zero. I don't have the home automation kit or anything else between the PI and PIMA. I don't know the version of PIMA. It is about 10 years old.

Great ! What about the command ? How did you find on your RPI the right serial port ? And which one is it ?

Sorry for the late response @Jens-Wymeersch. It is probably no longer relevant for you, but Hopefully, it would help others. The PI serial devices can be found in the "All Hardware" dialog. To open the All Hardware dialog do the following:

  1. Open the Hardware page: Open your Home Assistant instance and show hardware information.
  2. Click the "3 dots" icon on the top right of the page to open an options dropdown menu.
  3. Click the "All Hardware" option. It will open a modal dialog.
  4. Type "USB" in the "Search hardware" field to see just relevant devices. Scroll toward the bottom of the list.

I do not see this issue happening for a while now, so unless others still see it, I suggest closing this issue.

I don't know what fixed the issue. The code changes, the use of HomeAssistant AddOn, or the change of hardware that I described here: https://github.com/deiger/Alarm/pull/20#issuecomment-1258626221

In any case, I suggest closing this issue.
