We identified a few places where blocking operations (e.g., the list snapshots API endpoint) that may starve the network request accept loop in some realistic scenarios, we'll move those out to their own separate thread to avoid such blockage. FWIW, it would be still interesting to see a few metrics/CLI outputs from an affected system to hopefully ensure that there's nothing additional to that problem. - `head /proc/pressure/*` for some general info if the system is overloaded - `ls /var/lib/proxmox-backup/jobstates` just out of interest - `ss -tlpn` to see if another (old) proxy process is still accepting - `uptime`
