FRR crash when with SNMP

I have vyos configured with snmp v2 and have Solar Winds Orion as SNMP monitoring when server tries to poll the vyos device then the frr crash, below the logs, after that none of the routing protocols worked, so i posted as a bug as it seems to be one.

routerman@polux:~ sho ip bgp summary % BGP instance not found routerman@polux:~ sho ip ospf su

Invalid command: show ip ospf [su]

routerman@polux:~$ sho ip ospf neighbor
% OSPF instance not found

High CPU usage by bgpd when snmp is active

thanks Followed that thread and applied the workaround
