Subject: [quagga-users 12831] BGP stuck in clearing state
Hi,
I am seeing a strange issue of bgp flapping on my box. Am using quagga 0.99.16 version. The bgp peering is done with the route reflector handling some 100 routers. The flapping happens after 3-4 days of running bgpd process.
Show ip bgp summary at that point shows ::

The status becomes clearing.
Also the memory utilization of bgpd process becomes huge. Reaches to 36 G from 4 G . The show memory output at that time is :: ( Look at the Link Node & Hash Bucket).
