[ovirt-users] vdsm IOProcessClient WARNING Timeout waiting for communication thread for client

[Bill James]

We have an ovirt system with 3 clusters, all running centos7.
ovirt engine is running on separate host, 
ovirt-engine-3.6.4.1-1.el7.centos.noarch
2 of the clusters are running newer version of ovirt, 3 nodes each, 
ovirt-engine-4.0.3-1.el7.centos.noarch, glusterfs-3.7.16-1.el7.x86_64, 
vdsm-4.18.11-1.el7.centos.x86_64.
1 cluster is still running the older version, 
ovirt-engine-3.6.4.1-1.el7.centos.noarch.

Yes we are in the process of upgrading the whole system to ovirt4.0, but 
takes time....

One of the 2 clusters running ovirt4 is complaining of timeouts, vdsm 
talking to gluster. No warnings on the 2 other clusters.
