--- Comment #18 from Xavier Hernandez <xhernandez at datalab.es> ---
Does it also happen with a 2+1 (total 3 bricks) configuration ? I want to
identify the smallest configuration that has the problem to reduce noise.

The number of parallel reads that cause the problem varies with the
configuration ?

If possible, it would also be interesting to test some configurations:

* All bricks and clients on same server (this seems to work from a previous
test)
* All bricks on same server and the client in another one
* Bricks on different servers, the client on one of them
* Bricks on different servers, the client in another one

Seeing which configurations fail and what bricks fail on each configuration
could give us additional information.

Meanwhile I'll try to do some more tests to see if I'm able to reproduce it.
