Vyos High memory utilization


I’m using Zabbix for monitoring and I got this notification for Vyos

The system is running out of free memory.

Then I can’t collect SNMP data from it anymore ?

How to check that everything is ok ? or how to fix this ?

I’m using


Please I need your help

Hi @Zurattos
Could you please share this outputs from your router (VyOS):
ps aux --sort -%mem | head -20

ps aux --sort -%cpu | head -20

free -ht

free -ht
total used free shared buffers cached
Mem: 1.9G 500M 1.5G 46M 63M 149M
-/+ buffers/cache: 286M 1.7G
Swap: 0B 0B 0B
Total: 1.9G 500M 1.5G

I should see how much memory SNMP is using but it was stopped by itself once I had the memory issue

Update to 1.2.9 VyOS Community

So this is the only solution left ?

and SNMP can cause such an issue on Vyos ?

As I remember it was a bug with memory utilisation + bgp full view + snmp
Or it could be network driver issue.
I don’t now is it this case.
If you want to use outdated releases it will be difficult to get answer/solution and reproducing the bug.
I prefer to start with system update as I don’t remember reports regarding memory after 1.2.5
The better choice is 1.3.2 at the moment
