 Description   

Steps to reproduce:

  1. Install NetBird agent on the server.
  2. Link the agent2 to a server with a private IP in the NetBird VPN.

Result:

It happens only for a single server within our infrastructure. I stopped the agent after using 91.3496 % of our 32GB RAM.

Expected:

Memory usage should be moderate.

Hello, do I understand correctly that you have several servers with agent2 connecting to zabbix server using NetBird VPN and only one of them is having memory problems ? In that case are there any configuration specifics or agent checks that are used only with this server ?
