Running v6.11 on my CCR routers. My heaviest loaded routers are a PPPoE server and another is a BGP core router. Both seem to list one CPU core at 100 percent CPU usage 24/7. I cant help but wander if neither PPP or BGP is capable of using multi-cores?

They are multicore optimized. Maybe something else is causing this, please make a supout.rif file and send to support.

you can see per-cpu profiling in Terminal: for my CCRs, 100% of one core uses 'management' process. any info from support?

Huh, when did BGP become multicore optimized ?

BGP seems to max out one CPU at a time, I'm running 6.11 of this router and the maxed out core is always running the BGP process.

I founded the same issue with scripts execution.

I upgrade from 6.9 to 6.11 and now the RouterOS uses 100% CPU (in PROXMOX) and is unaccessible.
Same on 6.12

No Routing no Terminal no Winbox... not sure what uses the CPU...

I have same problem, cpu core 34 is always over 90% and completely router have problem because of that.

[admin@FTTH/B GW] /tool> profile cpu=34
NAME CPU USAGE
firewall 34 91.5%
networking 34 1.5%
winbox 34 0%
management 34 0%
routing 34 0%
idle 34 6.5%
profiling 34 0%
queuing 34 0.5%
unclassified 34 0%

look at your firewall rules. for example, do you use 'connection-limit'?

Hi, I don't use connection-limit. I have two drop rules and about 20-30 accept rules. Problem also persist when I disable all filter rules.
