Hi Marc,
It's busy processing snapshot contexts, I think it's more or less
the same issue that you reported in "ceph node crashed with these
errors "kernel: ceph: build_snap_context" (maybe now it is urgent?)".
Did "ceph: build_snap_context 100020c9287 ffff911a9a26bd00 fail -12"
errors go away?
How many snapshots do you have now?
Did you file a tracker ticket? It's better to have all details in one
place rather than scattered across different threads on the list.
Adding Jeff and Zheng, who can take a closer look.
Thanks,
Ilya
