We have updated our hypervisors with yum. This included an update ov vdsm also. We now are with these version:
vdsm-4.16.7-1.gitdb83943.el6.x86_64
vdsm-python-4.16.7-1.gitdb83943.el6.noarch
vdsm-python-zombiereaper-4.16.7-1.gitdb83943.el6.noarch
vdsm-xmlrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-yajsonrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-jsonrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-cli-4.16.7-1.gitdb83943.el6.noarch

And ever since these updates we experience BIG troubles with our fibre connections. I've already update the brocade cards to the latest version. This seemed to help, they already came back up and saw the storage domains (before the brocade update, they didn't even see their storage domains). But after a day or so, one of the hypersisors began to freak out again. Coming up and going back down... Below you can find the errors:
