Where can I find the coredump file ?<br>
<br>
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.<br>
<br>
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 ...<br>

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) :<br>

It seem to be a network interface problem :<br>

I'm using GlusterFS since many years and never see this problem, but
this is the second time in one week ...
I have 3 volumes with 2 bricks and 1 volume crash with no reason,

<pre wrap="">Did you observe the crash while mounting the volume? Or can you be more
specific on what were you doing just before you saw the crash? Can you
please share the output of `gluster volume info <VOLNAME>`?

<pre wrap=""> I just have to stop/start the volume to make it up again.
The only logs I can find are in syslog :
