fort v1.5.1-7 crashing at 2d validation cycle starting

[65007]

I'm running FORT validator fort v1.5.1-7-g274dc14 in Ubuntu 20.04 (compiled), with 4G RAM.

Everything starts Ok, the first validation cycle completes without issues (I'm able to connect routers to it and wok as expected)... but right when 2d validation cycle starts the process crashes (i've set the validation interval to 15 minutes in this case):

root@zulu:~# tail -f /var/log/fortd.log

Rats; didn't mean to close.

But it's likely fixed. Can you try it?

(Please recompile from the autogen.sh step, so the version number updates properly.)

Did compile it again and now seems to be working fine.
Gone through over 3 validation cycles and process still up and running properly.
Thanks very much for the fix !

Great job with the validator by the way !
