[Gluster-devel] Gluster crash

[Samuel Hassine]

Hi all,

Our service using GlusterFS is in production since one week and we are
managing a huge trafic. The last night, one of the Gluster client (on a
physical node with a lot of virtual engines) crashed. Can you give me
more information about the log of the crash?

Here is the log:

I just want to know "why" Gluster crashed.
