      Good point, we've looked at that, but can't see any message regarding 
OOM Killer:

root@st0:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.4 LTS
Release:        18.04
Codename:       bionic
root@st0:~# grep -i "out of memory" /var/log/kern.log
root@st0:~#

kind regards,

After unsetting the norecover and nobackfill flag some OSDs started 
crashing every few minutes. The OSD log, even with high debug 
settings, don't seem to reveal anything, it just stops logging mid 
log line.
POOMA U, but could the OOM Killer be taking them down?
