Hi Michael,

I've changed my image a few times since the last crash, too.  But, it's occurred again.  Here's what I get.  Interestingly, it only seems to happen when the ovms module is in the car, not sitting on my desk.  So, perhaps a timing issue introduced by the processor load of CAN traffic?  This crash was a web fetch, but it also occurred when I telnet'd into the module, about a half dozen characters into typing a command.  At that time, the HUD was running, too.  (The command was intended to turn off ext12v power, in order to disable it.)  I didn't capture that crash's console traffic, but the symptoms and timing seemed about the same.  There's a several second delay between the 200 error and the crash.

Greg,

I just realized your crash like my latest one also had that STA disconnect reason 200 entry. So maybe that's not memory related.

I can't get a usable addr2line output from your backtrace, I think my .elf file is too different from yours (lots of excluded components here).

Can you provide that using your build?

Thanks,
Michael

Hi folks,

The module has been sitting on my desk, simply minding its own business.  During dinner I thought I'd poke at the webserver a bit, connecting to the module via the home wifi network (i.e. not the AP side).  That's usually pretty reliable.  Wasn't this time...

The "failed to allocate socket" message suggests the crash was a down-stream result of being out of memory, but posting here to verify that.  Wonder if the error's recovery is possible, or do we simply need the extra memory so it doesn't happen in the first place.
