require help for two problems:failing to caps release/failing to cache pressure release
I use cephfs mount in kubernetes, the issue is that some apps getting stuck at client side when two cases above arise.
could you please some thoughts about root cause?
ceph version: L12.2.8
client kernel: 4.9.88-1+deb9u1 debian9
server kernel:4.9.88-1+deb9u1~bpo8+1 debian8
