RHEL7: On Red Hat nfs server with delegations enabled (leases-enable == 1) we are seeing periodic "FS: file-max limit XXXXX reached" messages

Solution Unverified - Updated -


  • Periodically on the NFS4 server with delegations enabled we see FS: file-max limit XXXXX reached messages. During this time an NFS client with a share mounted from that server cannot open files.


  • Red Hat Enterprise Linux 7 (NFS server)
    • delegations enabled (/proc/sys/fs/leases-enable == 1)
  • Red Hat Enterprise Linux 7 (NFS client)
  • NFS4.x
