Subject: [ceph-users] Luminous 12.2.12 "clients failing to respond to 
capability release"


I am getting this error 

I have in two sessions[0] num_caps high ( I assume the error is about 
num_caps ). I am using a default luminous and a default centos7 with 
default kernel 3.10. 

Do I really still need to change to a not stock kernel to resolve this? 
I read this in posts of 2016 and 2019, yet I also saw some post on 
tuning the mds.
