I started FIO in client/server mode with two clients running 24 jobs
each on individual LUNs. After a while, FIO fails with the following
assertion, even though the jobs are still running on both the clients.

# fio --client=client1 --remote-config=/root/all_powerpath.fio
--client=client2 --remote-config=/root/all_multipaths.fio

Also sometimes the job information gets mixed up from both the clients
as above.

Thanks for your support.
