Signing clarification

[Nigel31]

Could some one confirm / clarify for me please.
I have a node that has #define MY_SIGNING_REQUEST_SIGNATURES defined.
My sensebender serial gateway does not have this definition set.
My node seemingly is randomly watchdog rebooting, which I have been endevouring to fault find for a while. It happened to occur whilsyt I was online with it, the last messages relating to signing exchanges.
my question is, Do I have to completely wipe my gateway eeprom, and reflash the gateway sketch to allow unsigned communications to this particular node? by removing #define MY_SIGNING_REQUEST_SIGNATURES, or Could I just delete the signing defines on the node ( didnt seem to work when I tried it)

the nodes definitions are:
#define MY_SIGNING_SOFT
#define MY_SIGNING_SOFT_RANDOMSEED_PIN A6
#define MY_SIGNING_REQUEST_SIGNATURES
