Michael, Does TLS periodically require some potentially expensive cryptographic operation such as generating a new key? Perhaps there is a difference in the period specification for MBEDTLS vs WolfSSL. There are relatively expensive operations done when the connection is established; those don't seem to cause WDT or queue overflow. So if there is a periodic expensive operation, the problem must be that doing it in the midst of some other operation causes the problem. -- Steve On Sun, 11 Apr 2021, Michael Balzer wrote:
Steve,
I can confirm an increase of these events since we changed to WolfSSL, about once every three days currently for me. The frequency was much lower before, more like once or twice per month.
I've disabled TLS on my module now and will report if that helps.
