How over-optimized is your build? Straight binary install or did you build it all with -O999 and suchlike?
xfs backend. fuse 2.8.1
fuse libs at the very least can be ruled out as a cause, since glfs 3.0.x doesn't use them, it connects straight to /dev/fuse, AFAIK.
Same server, same configuration, same tests, with gluster 2.9 => no reboot.
It's a little concerning that a process only communicating with kernel space through /dev/fuse can cause a reboot like that. One of the key points of fuse was to create enough separation to make that impossible...
Do you get a core dump? Is there a core.* file in the root directory ? Gordan
