[Gluster-users] A glusterfsd process crashed(?)

[Isamu SUZUKI]

Hello guys,

I'm an administrator of our GlusterFS replicated storage on AWS.
The version of GlusterFS is 3.4.1 ( all gluster servers and all clients )

A process of glusterfsd crashed.
And the same process crashed too  after 1 month of the former crashed.

I've checked /var/log/glusterfs/bricks/our-context.log.
