Hi John,
I have snip out the ipaddress, I'm using cephfs clients. And as of now using 7 clients, it will increase. The kernel version i'm using is 3.10.0-514.16.1.el7.x86_64 in all ceph nodes(mds/osd/mon/clients). And the os version i'm using is Centos 7.3 Regards, Suresh ---- On Mon, 14 Aug 2017 19:54:25 +0530 John Spray <[email protected]> wrote ---- On Mon, Aug 14, 2017 at 3:13 PM, psuresh <[email protected]> wrote: > Hi, > > Suddenly I've faced cache pressure on my production ceph cluster. mds > running on 8GB vm. > > After restarted the mds service, HEALTH come to OK.

What client is in use? By the way, are those the actual messages or did you snip out the second half of the IP address for privacy? If that's how they really appeared it's probably a bug.
