      I've just noticed that on version 3.4.2RC2 an M122 call causes a reset of the board.

      Board: Duet 2 WiFi (2WiFi)
      Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.2rc1 (2022-07-06)
      Duet WiFi Server Version: 1.27beta1
      Duet Web Control 3.4.2-rc2

      If I run an earlier version of Duet2CombinedFirmware.bin it doesn't happen ( I didn't go back with DWC or Wifi)

      I do use quite a lot of global variables, but the stack reports on earlier versions seem OK to me?

      M122 report with 3.4.2RC1 (installed immediately after a reset when trying RC2)

          @owend I confirm this is a bug. I have put a new firmware build for Duet 2 at https://www.dropbox.com/sh/7tf55ax00ky1pyx/AAA_eVJE20oYUON_gjKhCHsja?dl=0.
