Observed dCache v4.2 yielding the following error:

RENEW with expired lease should return NFS4ERR_EXPIRED, instead got NFS4ERR_STALE_CLIENTID

With stack-trace:

Traceback (most recent call last):

    self.runtest(self, environment)

    raise testmod.FailureException(msg)
FailureException: RENEW with expired lease should return NFS4ERR_EXPIRED, instead got NFS4ERR_STALE_CLIENTID

pynfs build #8498: details.

The problem appears to be intermittent, suggesting a race-condition in the NFS server code.

As a temporary fix, I've added RENEW3 to the list of excluded NFS v4.0 tests

Reports of this failure on master branch: pynfs build #8507: details.

Disabling RENEW3 on master, too.
