[Gluster-users] Memory leak in gluster 5.4

[Diego Remolina]

Are you using FUSE mounts to access the file system? I have observed the
same issue all the way from 3.x series to 4.x series. I have to reboot
servers monthly, at most every 45 days because gluster keeps eating the ram.

As you can see, 30 days in we are right at around 30GB of RAM used.
