Thanks Dan,
I'll use these ones from Infernalis:[global]
osd map message max = 100
[osd]
osd map cache size = 200
osd map max advance = 150
osd map share max epochs = 100
osd pg epoch persisted max stale = 150

I wouldn't run with those settings in production. That was a test to squeeze too many OSDs into too little RAM.
Check the values from infernalis/master. Those should be safe.

[global]
osd map message max = 10
[osd]
osd map cache size = 20
osd map max advance = 10
osd map share max epochs = 10
osd pg epoch persisted max stale = 10Are there are large production deployments running with these or similar settings?Thank you,
