[FROG] [SOLVED] [BUG] Re: ospf6d issues (crashes getting routes from my network)

Can we turn on:

debug ospf6 spf
debug ospf6 route
debug ospf6 flooding
debug ospf6 lsa

The original stack-trace was very odd imo.  It didn't make sense to
me.  Maybe some debug will shed some light?   In any event you can
join us in the FRRouting slack for a quicker turnaround ( goto
https://frrouting.org and click on the slack link ).

thanks!
