Hi Martin,
looks like a bug to me.
You might want to remove all custom settings from config database and try to set osd-memory-target only.
Would it help?
Thanks,
Igor

Quoting Martin Mlynář (nexus+ceph@smoula.net):
Do you think this could help? OSD does not even start, I'm getting a little lost how flushing caches could help. I might have mis-understood. I though the OSDs crashed when you set the config setting.
According to trace I suspect something around processing config values. I've just set the same config setting on a test cluster and restarted an OSD without problem. So, not sure what is going on there.

I've compiled ceph-osd with debug symbols and got better backtrace:

But there I'm stuck. GDBing c++ code is a really dark sorcery for me.
Other get_vals look fine, maybe get_val<*Option::size_t*> is the problem? It looks like trouble outside of ceph - what system are you testing on? This is debian with official debian build from buster-backports. Maybe some of debian's patches?
