    I've been releasing all builds on my server including the fix since

                                            <pre class="moz-quote-pre" wrap="">Hi folks,

Well, the module updated to 3.2.007 last night.  I just checked on it,
and it appears that it didn't exactly survive.  Crashed while running
the autoconfig script.  Log with two cycles attached.

I tried renaming the /store/events directory to /store/was_events since
it seems like Duktape was getting in the way, but that didn't resolve
the crash.  I manually enabled wifi so I could manage the module, and
moved it back to 3.2.005 from the other partition.  Seems stable again.

The car is going into the Service Center tomorrow (the perennial issue
with 1146 alerts), so I need to have the module stable so that I can
keep an eye on it.  Going to leave it on 3.2.005 for now, unless someone
has a quick fix in the next few hours...

Otherwise, any ideas for troubleshooting after I get the car back back
(hopefully end of day)?

Greg
