    Mark,<br>
    <br>
    I've been running the new for-v3.3 version this week on both of my
    modules without ppp issues.<br>
    <br>
    Duktape still occasionally runs into the null/undefined issue with
    for…in:<br>
    <br>
<a class="moz-txt-link-freetext" href="https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/474#issuecomment-744005044">https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/474#issuecomment-744005044</a><br>
    <br>
    for…in normally doesn't throw an error even if you run over null or
    undefined.<br>
    <br>
    I think both could still be the SPIRAM bug, now probably only
    occurring with very specific conditions. We build with LWIP using
    SPIRAM as well, so the PPP instance is allocated from SPIRAM also.
    Reallocating the instance on each new connect implies a higher
    chance of triggering the problem if it's address specific. The
    Duktape stack object addresses vary continuously with the running
    event handlers and user interactions, so that also has a high chance
    of occasionally triggering an address specific bug.<br>
    <br>
    We need to test the revision 3 ESP32 on this.<br>
    <br>
    Regards,<br>
    Michael<br>

      <div class="">Comparing the master vs for-v3.3 branches, the only
        thing that changed related to ppp is that in 3.3 the ppp object
        is dynamically created and destroyed, while in master it is
        statically allocated at boot. The ppp code is so simple, and I
        can’t see how that could be a problem. Perhaps related to
        position in memory, and some other memory corruption?</div>
      <div class=""><br class="">
      </div>
      <div class="">Anyway, I changed it to not destroy the ppp object
        when the gsm connection is lost, but merely shutdown the ppp
        (which is what master branch does). While it is still
        dynamically allocated, it is no longer as dynamic (being created
        just once at startup of the cellular system). I’ve never managed
        to reliably repeat this problem in my environment, but I think
        this should help.It has been running on my desktop test unit for
        the past four days without issue.</div>
      <div class=""><br class="">
      </div>
      <div class="">That code is committed now. I would appreciate it if
