Hi, ubuntu 12.04.01 LTS 64bit openstack Essex glusterFS 3.3 We gave 2 openstack nodes which glusterfs share on /var/lib/nova/instances When I put a lot of network traffic (100Mbps) to 1 or more instances on the openstack nodes, the instances stop responding after some time (+/- 20min). I can not connect with VNC or which ssh to the intances that do not response, only after a reboot of the instance, everthing starts working again. I guess it has something to do with the network load on the instances, this because other instances keep working. How can I debug this of better solve this issue? Grtz, Jiri Hoogeveen
