  Hi,
I forgot to look in the /var/log/messages file on the host ! What a shame :/
Here is the messages file at the time of the error : 
https://gist.github.com/fsoyer/4d1247d4c3007a8727459efd23d89737
At the sasme time, the second host as no particular messages in its log.
Does anyone have an idea of the source problem ?

https://gist.github.com/fsoyer/e3b74b4693006736b4f737b642aed0ef
searching for "Failed to acquire lock" I see a post about sanlock.log. Here it 
is at the time of the restart : 
https://gist.github.com/fsoyer/8d6952e85623a12f09317652aa4babd7
(hope that you can display this gists)

First question : there is all the days those message "delta_renew long write 
time".  What does this mean ? Even if I suspect some storage problem, I don't 
see latency on it (configuration described bellow).
Second question : what append that force some VMs (not all, and not and the 
sams host !) to restart ? Where and what must I search for ?
Thanks

Configuration
2 DELL R620 as ovirt hosts (4.2.8-2) with hosted-engine, also members of a 
gluster 3.12.13-1 cluster with an arbiter (1 DELL R310, non-ovirt). The DATAs 
and ENGINE storages are on gluster volumes. Around 11am, I do not see any 
specific messages in glusterd.log or glfsheal-*.log. Gluster is on a separate 
network (2*1G bond mode 4=aggegation) than ovirmgmt (2*1G bond mode 1=failover).
