HI, I have a strange question.
Stand alone Proxmox server with 120 lxc container. Every container act as node for a mesh network (one daemon for every container). Every node send just some byte to other node on specific event, but every container has from 8 to 32 active connection with other node on network ( some twin server around the world). This means every server must have minimum 1200 active connection with other node EVEN every connection send only few byte a day. I'm unable to have this connection active in same time.. How I can tune up interface and/or tcp to do this? I have put 2x1GB uplink and send half node for every uplink... now it's better but not perfect.. There are sysctl option I can set?
 
I don't receive error.. simple some node can connect to net and sync... when finish, some other can do it... on log, node awaiting connection SEAMS FREEZED, like connection request was on a queue.. I know it's too strange..
