I compared 4.1.5 and 3.12.15, there's no pb with 3.12.15 client.

Did you see this behaviour with previous Gluster versions?

I encounterd an issue on production servers using GlusterFS servers 5.1 and clients 4.1.5 when several process write at the same time on a gluster volume.

With more than 48 process writes on the volume at the same time, they are blocked in D state (uninterruptible sleep), I guess some volume settings have to be tuned but can't figure out which.

The client is using op-version 40100 on this volume
Below are volume info, volume settings and ps output on blocked processes.
