After boot VyOS 1.2 (201809210337-amd64) after some days (2 or 3) I saw 1 CPU core at 100% usage because of charon. On that case logs like these were printed together with CPU usage.
Oct 16 05:41:51 ROUTER-BGP charon: 04[KNL] unable to receive from RT event socket No buffer space available (105)
Oct 16 05:41:52 ROUTER-BGP charon: 06[KNL] unable to receive from RT event socket No buffer space available (105)
Oct 16 05:41:54 ROUTER-BGP charon: 10[KNL] unable to receive from RT event socket No buffer space available (105)
Oct 16 05:41:55 ROUTER-BGP charon: 07[KNL] unable to receive from RT event socket No buffer space available (105)
I stoped the process IPSEC and everything continued working (BGP, OSPF, firewall).
After reboot the server, the process starts normally like below
There was 1 case that after server reboot, the charon started with high usage and with “charon: 04[KNL] unable to receive from RT event socket No buffer space available (105)” log and 2 BGP sessions (without MD5) don’t started. ->>> _https://forum.vyos.io/t/memory-leak-on-vyos-1-2-20180921-consumes-6gb-in-less-than-7-days/2619/14_
I’m using another server with version 1.2 (201807230337-amd64) and in a similar setup (BGP, VRRP, Firewall without OSPF). This server is working for 83 days, and today this process appeared with 100% cpu usage (about 22h ago).
What kind of info can I get to help diagnostic?
