For DNE testing on master branch, we are seeing a similar error:

I'm reopening this ticket because we are still seeing this issue or something that looks like it. See https://testing.whamcloud.com/test_sets/ea83e839-7f5d-48da-b284-2cba8c50d366 for logs for an ARM client testing session.

There is patch: https://review.whamcloud.com/37393 "LU-13184 tests: wait for OST startup in test_112" which may fix this problem.
