Crash report for vehicle module

My vehicle module stopped communicating with the server.  The app said it hadn't checked in 12 hours, so I went to look at its status page and the website for the vehicle module would not load.

My router said its IP address was allocated to Expressif Inc.

I power cycled the unit and it came right up.  Checked in with my server and the vehicle module website is working as expected.

I have automatic power management disabled, the 12v shutdown voltage is 11.5, the wakeup voltage is 11.9, and my 12v battery is reading 13v.  I calibrated the battery, so I don't think it was a low voltage shutdown.

Any ideas?

Device just crashed again.  Although I have the charge limit set to 69%, the car charged to 100% overnight.  Checking on the module it wasn't checking into the server and the vehicle module webpage wasn't responding.

Is it normal for modules to crash this much?
Last boot was 117193 second(s) ago

This is reset #69 since last power cycle

Detected boot reason: Crash (12/12)

Reset reason: Exception/panic (4)

Any way to stop the crashing?

Not sure if this helps find a root cause, but my module just crashed again when I hit stop v2 and start v2:

Maybe it's related to this issue? https://www.openvehicles.com/node/4234

The module wasn't working, online, or doing anything, so I connected via USB.  Specifically:

The LothOVMS wireless network was not appearing on my phone (the wifi SSID that the OVMS broadcasts)
The OVMS was not available on its dedicated IP address on my local network

The moment I connected via USB, I got the following output:

Now it's online, communicating with my server, pingable at its IP address, and broadcasting its own access point.  It looks like connecting via USB caused it to reboot.  12V is 12.3V.  Any ideas what could be going on?

Its status is this:
Last boot was 531 second(s) ago

Time at boot: 2024-10-22 23:28:40 CDT

This is reset #0 since last power cycle

Detected boot reason: PowerOn (1/14)

Reset reason: Unknown/unset (0) Crash counters: 0 total, 0 early

12v shutdown is 11.5

12v alert is 1.6 below a reference of 12.6

12v wakeup is 11.9

Wakeup test interval is 240s

Battery is showing 12.4 according to multimeter and OVMS (I calibrated the 12v battery)

Serial connector is screwed in, so it's getting power both from USB and from serial.  I disconnected the USB and it's still staying on now.

Happened again.  Grabbed the metrics and started reading the source to try to understand.  The Live view in Status showed the Network as none.  I tried a few soft reboots, and nothing fixed it.

I tried stopping and restarting the v2 server in the GUI and it didn't help at all.

I tried issuing some events:

• event raise network.up
• event raise server.v2.stopped
• event raise server.v2.waitreconnect
• event raise server.v2.connecting

None of these fixed the problem.  Network still showed None under the Live view, but clearly showed the network with -89 DBM on the Wifi view.  Connecting to the module via its IP to the web server also worked.

I then tried to reboot again, and the module stopped responding.  It was responding to pings, but nothing else.  The webUI was dead, it wasn't checking into the server... nothing.

I power cycled it and everything is back to normal.  I will continue troubleshooting when it happens again.  I disabled the AP hosted by the ovms module thinking maybe it was getting confused with both networks.  Now it's only starting as a client to my AP.

I did notice that the dBm is -74 after reboot, but was -90.3 in the metrics list during the event happening.  The car, module and AP didn't move--so that's quite a signal difference.

Taking notes for further investigation when it happens again:

System is in a WaitNetwork state here:
