Worked around it by doing a fail of the mds because I read somewhere
about restarting it. However would be nice to know what causes this and
how to prevent it.
ceph mds fail c

These are not excessive values, are they? How to resolve this?
[@~]# ceph daemon mds.c cache status
{
"pool": {
"items": 266303962,
"bytes": 7599982391
}
}
[@~]# ceph daemon mds.c objecter_requests {

On the client I have this
[@~]# cat /proc/sys/fs/file-nr

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.
