Here's the sequence of events:

So you don't get ESTALE, but you get EACCESS? You *might* be able to fix
this by setting the 'no_subtree_check' in your /etc/exports. I don't
remember the details exactly anymore, but nfsd/exportfs check more
intensively if a dentry is valid if this option is not given.
I don't remember seeing either ESTALE or EACCESS, just that there was a
message about stale file handles. I didn't save the messages I with
You said "Eventually a job fails with a 'permission denied'" and that is
access and not ESTALE?
Okay, this is a confusing point. When I cd to /l/hostname, the error
returned by the OS is "permissions denied". That's it. When I try to
mount the filesystem manually while watching the communications with TCP
dump, I see the server sending a "Stale File Handle" message back to the
client, but I don't see the words ESTALE or EACCESS explicitly in those
messages, or in the rpcdebug messages when turn on rpcdebugging.

Btw, which kernel version and file system is your nfs server running on?
Both servers and clients are running the same exact version of
everything, since they are using the same NFS root filesystem:
$ cat /etc/redhat-release
CentOS release 6.8 (Final)
$ cat /proc/version
Linux version 2.6.32-642.11.1.el6.x86_64
([email protected]) (gcc version 4.4.7 20120313 (Red Hat
4.4.7-17) (GCC) ) #1 SMP Fri Nov 18 19:25:05 UTC 2016
$ rpm -qa | grep -i nfs
nfs-utils-lib-1.1.5-11.el6.x86_64
nfs-utils-1.2.3-70.el6_8.2.x86_64
nfs4-acl-tools-0.3.3-8.el6.x86_64
I mean what is the file system the NFS server is running on?
Oh. Oops. ext4
