Quick Hit - NIC driver hang/reset under heavy load
One of the reasons it took me almost six months to relaunch the blog is that I kept running into instability problems at almost every layer. I didn’t know if it was hardware, Proxmox, GlusterFS, Longhorn, or K3S. The one thing in common is that it would happen when the system was under heavy load - backups, large file transfers, etc. Every time I thought I had the issues largely resolved, the new Proxmox node would stop responding.
