BFD+OSPF status in 2020

Hello,
I decided to give OSPF+BFD another try in 2020.
I am currently running the following scenarios:

  • CCR1016 ↔ CCR1016 (v. 6.45.9)
  • CCR2004 ↔ CCR2004 (v.6.47.3)

I have achived a running time of 7 days+ without issues, while in the past, at least with CCR1036, I couldn’t go past few minutes.
Anyone else is seeing this?
