MinSig

=== Both nodes Minsig ===
Try setting minsig on *both* nodes... I've seen this issue on my nodes
as well.
A word of caution - before doing any getandverify, change all minsig
values to 0 and make apply the changes after reboot or you could end up
manually editing the /etc/wiana.settings file, as some versions of
software report differently for minsig.
