This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/7f44a5c8-9635-11e7-b760-5254006e85c2.

The sub-test test_40 failed with the following error:

test failed to respond and timed out

from the following stack trace it looks like the client hung during NFS access:
