Hi Michael,

When the vehicle is not set to poll and only receiving can1 messages I managed to obtain a 10Mb file - logging a variety of signals some with 10ms timing without any issues. However, when polling and can1/can2 are operating and I try to log the same signals I get the following crash trace. I would suspect the underlying cause of the crashing relates to both buses being active as opposed to the polling but that may not be the case.

Last crash: abort() was called on core 0 Backtrace: 0x4008e627 0x4008e8c1 0x400e7060 0x40083f6a Event: ticker.1@esp32wifi 0 secs WDT tasks: IDLE1|OVMS DukTape
