Hi David,
with so little information it's hard to tell, but given that there are several OPEN and UNLINK operations, it could be related to an already fixed bug (in recent versions) in open-behind.
You can try disabling open-behind with this command:
# gluster volume set <volname> open-behind off
But given the version you are using is very old and unmaintained, I would recommend you to upgrade to 8.x at least.
Regards,
Xavi

________Hello,We have a GlusterFS 5.13 server which also mounts itself with the native FUSE client. Recently the FUSE mount crashed and we found the following in the syslog. There isn't anything logged in mnt-glusterfs.log for that time. After killing all processes with a file handle open on the filesystem we were able to unmount and then remount the filesystem successfully.Would anyone have advice on how to debug this crash?
