On the client I have this [@~]# cat /proc/sys/fs/file-nr 10368 0 381649 -----Original Message----- 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.
