[Gluster-users] Gluster 4.1 servers - KVM Centos 7.5 clients - replica 2 - continuous healing taking place.

We have a replica 2 setup using glusterfs-4.1.1-1 which we use to store VM
files. The Gluster
clients are Centos 7.5 using gluster "url" setup for the VM disks - e.g.

   <disk type='network' device='disk'>
     <driver name='qemu' type='raw' cache='none' io='native'/>
     <source protocol='gluster' name='glu-vol02-lab/build-plugin-01'>
       <host name='gluvm-vol02-b' port='24007'/>

We have the problem that gluster on the 2 brick server keeps on running
healing operations - it's
a bit hard to understand why as we cannot see any drops in network traffic
between the 2 bricks
(either errors or bandwidth issue).

   - Is there a fundamental versioning conflict ?
     (libvirt-daemon-driver-storage-gluster-3.9.0-14.el7_5.5.x86_64 vs.
   gluster 4.1)

   - Is there a limit to how many clients a gluster server can handle ?

   - Some setting we need to adjust ?

I hope someone has an idea,
