@Anoop,

Where can I find the coredump file ?

The crash occurs 2 times last 7 days, each time a sunday morning with no
reason, no increase of traffic or something like this, the volume was
mounted since 15 days.

The bricks are used as a CDN like, distributting small images and css
files with a nginx https service (with a load balancer and 2 EC2), on a
sunday morning there is not a lot of activity ...

Volume infos:

I don't know if there is a link with this crash problem, but I have
another problem with my 2 servers that make GluserFS's clients
disconnected (from another volume) :

It seem to be a network interface problem :
