Description

Hello, we have a problem I`ve recentrly described on VyOS forum

https://forum.vyos.io/t/seems-bgpd-process-consumes-a-lot-of-memory-or-memory-leak/9285/1

in short, when bgp starts, it eats a bit more 400M memory. After a day - consumed memory reaches 1Gig.
After 5-6 days, consumed memory reaches 3,5 - 4.0 Gigs and continues with growing.

Some outputs has provided in forum thread. If you need additional outputs/info, please ask.
