      <div dir="ltr">How are we going with this investigation?
        <div><br>
        </div>
        <div>I've been following along mostly and have been periodically
          going over the poller code trying to work out if there are any
          points where there could be timing issues with long-held
          mutexes (or even deadlocks).  I did push up some small tweaks
          recently but there was no aha! moment.</div>
        <div><br>
        </div>
        <div>I have been working on some changes that would move forward
          on the idea of building a vehicle implementation from duktape
          scripts... and I had been getting some points where ovms went
          berserk, kicked out the ssh session and stopped responding on
          ssh http but then eventually came back (without a reset) after
          some minutes. The script was simply adding a new
          PollSeriesEntry which then uses the dbc decoder (with
          improvements) to decode to metrics, noting that the script is
          setup only and that there are no call-backs into the duktape
          engine/task.</div>
        <div> </div>
        <div>Anyway, those patches mentioned above seem to have resolved
          that issue with the hangups which is why I made the p/r.</div>
        <div> </div>
        <div>BTW I have been running my Ioniq5 with the latest of the
          timing patches for a while now.</div>
        <div><br>
        </div>
        <div>Because of the correlation of the bus issues with the
          poller changes, I am still concerned that the poller changes
          are contributing to the problem (even if not directly causing
          it), so would be happy to chase down any leads people might
          have. </div>

                              <div> </div>
                              <div>I did indeed have B2604-00, along
                                with nineteen others. Most of these
                                mention CAN errors, and it seems
                                plausible that low 12v could be a common
                                cause.</div>
                              <div> </div>
                              <div>Do you think this rules out a poor
                                OVMS OBDII connection? I'm thinking if I
                                have high resistance in that connector,
                                then OVMS will experience low voltage
                                but the rest of the car modules will
                                have good voltage.</div>
                              <div> </div>
                              <div>However I see codes that suggest
                                communication errors between Nissan
                                modules:</div>
                              <div>C118C-01 ABS Brake: Malfunction is
                                detected in VCM system. Control module
                                communication issue.</div>
                              <div>B2064-00 BCM Shift PN Diag CAN:
                                Park-Neutral position switch signal
                                discrepancy</div>
                              <div>C1A70-01 BRAKE: Malfunction is
                                detected in ABS actuator control unit
                                system</div>
                              <div>U1266-02 MULTI AV: Malfunction is
                                detected between the AV control unit and
                                TCU</div>
                              <div>U0428-00 AVM: Invalid data received
                                from steering angle sensor module</div>
                              <div> </div>
                              <div>So I'm thinking perhaps the whole car
                                briefly had low voltage.</div>
                              <div> </div>
                              <div>To try to fix this, I cleaned the 12v
                                battery terminals and performed a long
                                charge. After clearing the codes, I have
                                only two codes that reappear.</div>
                              <div> </div>
                              <div>P317E-00 EV/HEV HV Battery System
                                EVC-249 (perhaps caused by <a href="https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/1061" rel="noopener noreferrer" target="_blank">#1061</a>)</div>
                              <div>U1A06-15 TCU Communication incorrect
                                calibration (probably because I've
                                removed its antenna)</div>
