[Gluster-users] gluster 3.12.8 fuse consume huge memory

[Darrell Budic]

I’m not seeing any leaks myself, been on 3.12.13 for about 38 hours now, still small.

You did restart that node, or at least put it into maintenance (if it’s ovirt) to be sure you restarted the glusterfs processes after updating? That’s a lot of run time unless it’s really busy, so figured I’d check.
