infrastructure:
2 vyos routers running on virtualbox. They are connected over ethernet interfaces with ospf running.
problem:
after a few hours ( between 5 and 10) the ospf neighborship breaks and i get the trap:
ospfTrapIfSateChange trap sent: x.x.x.x now Down
when i run "show ip ospf neighbor" it says ospf process not enabled. i can ping across the interface between the 2 routers.
Now if i reboot this router, every thing becomes OK.
i have also noticed that when this error occurs i can no longer do an ssh to this router.
this error can occur on any of the 2 routers.
