I've done some stack size watching and pushed some optimizations: - CanRxTask: 4K → 1K - COrx Task: 4K → 3K [+config] - COwrk Task: 4K → 1.5K [+config] - Vrx Task: 4K → 3K [+config] - Tmr Svc: 6K → 3K Much better now, nearly no crashes during normal operation, so most crashes now have been memory related (I had normally 2-3 crashes during a normal drive). A single crash I had when getting back home may have been due to my PC reconnecting to the webserver in parallel to my phone. There are more stacks we possibly can reduce: - SIMCOMTask normally maxes out at 2.3K (of 4) - wifi ditto - mdns normally uses 1.7K of 4 (no config for that one, defined in esp mdns_private.h) These should normally have no larger stack requirements as their operation is pretty much fixed, so that would be another 4.5 - 5K to get. As stacks need to be pinned to the internal RAM, hw3.1 also should benefit from these optimizations.
