Description
If I run the "suites/tiobench.sh" suite with kclient I sometimes
(or maybe always) get a failure, after the suite has completed.
Here's a short yaml file that should reproduce it:
roles: - [mon.a, mon.c, osd.0, osd.1, osd.2] - [mon.b, mds.a, osd.3, osd.4, osd.5] - [client.0] kernel: mon: branch: testing client: branch: testing tasks: - install: - ceph: - kclient: - workunit: clients: all: - suites/tiobench.sh
Below is an output excerpt that demonstrates the problem.

This test is part of the kernel suite that runs nightly, and AFAICS never fails there... :/
