Gluster samba panic?

["Glomski, Patrick" <patrick.glomski@xxxxxxxxxxxxx>]

I am running an SL7.2 machine with the samba version 4.2.4 hosted at download.gluster.org. I use the samba glusterfs virtual filesystem to connect to a 3.6.6 gluster array. Periodically (every hour or so when in use) smbd will panic, crash, and restart. Users don't seem to be complaining about it, but the fact that it keeps crashing is worrisome. Does anyone know if this issue has a bug or is fixed in a newer version of the glusterfs vfs plugin? I've attached an excerpt from /var/log/messages and a core dump.

# cat /etc/redhat-release; echo "samba: $(smbd --version)"; echo "vfs: $(rpm -qa | grep vfs-glusterfs)"

Scientific Linux release 7.2 (Nitrogen)
samba: Version 4.2.4
vfs: samba-vfs-glusterfs-4.2.4-6.el7.centos.x86_64

/var/log/messages panic
