Wondering if somebody would be able to apply simple patch that
periodically resets StupidAllocator?
Just to verify/disprove the hypothesis it's allocator relateted

Quoting Wido den Hollander (wido@xxxxxxxx):
Just wanted to chime in, I've seen this with Luminous+BlueStore+NVMe
OSDs as well. Over time their latency increased until we started to
notice I/O-wait inside VMs.
On a Luminous 12.2.8 cluster with only SSDs we also hit this issue I
guess. After restarting the OSD servers the latency would drop to normal
values again. See https://owncloud.kooman.org/s/BpkUc7YM79vhcDj
Reboots were finished at ~ 19:00.
