Mmmmm no, for me the same problem.
Rollback 2.2.4 -> 2.2.1 and works great.

You have 30% of runnable process getting stalled due waiting for IO, that naturally should not cause the request accept future to get starved but is the reason for why it happened with the current (or better old) architecture. Increasing available memory, so that the page cache can hold more entries, could already relieve that system a bit. We improved on the reproducer we got locally by simulating a higher latency disk using dm-delay on a small single core VM. For one we made the libpve-storage-perl do more efficient list-snapshot requests if they can be filtered by VMID, and on the PBS side we moved most operations that cause IO (and are related to backup groups/snapshots) to a separate thread pool so that the main thread should be less congested/blocked. The results got packaged and uploaded to our test repositories and are available with: - proxmox-backup-server version 2.2.4-1 - libpve-storage-perl version 7.2-7 It'd be great if you could try out those and report back if they actually helped in your setup(s) too. cheers, Thomas _______________________________________________ pbs-devel mailing list pbs-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel
