BGP crash

Description

Currently running a recent nightly build

I was removing two BGP peers and on commit it killed the entire BGP process. VRRP was still going and primary on that router too. A bit ugly

All I did was enter two commands to delete BGP neighbors. i.e.

delete protocols bgp 65003 neighbor 2001:504:1::a500:5976:1
delete protocols bgp 65003 neighbor 198.32.160.107
commit

and all hell broke loose. BGP completely stopped.

Had to reboot and it came back ok.

Deleting neighbors, as such, works, so we need an exact reproducing procedure.

I'm putting this on hold until we receive a reproducible procedure for testing this.

I think we can close this task.
Nothing like that has happened in the last few months.
