[ovirt-users] Engine HA-Issues

[Sven Achtelik]

Hi All,

after running solid for several month my ovirt-engine started rebooting on several hosts. I've looked into the hostend-engine -vm-status and it sees that the engine is up on one host but not reachable. At the same time I can access the gui and everything is working fine. After some time the engine is shutting down and all hosts are trying to start the engine until one is the winner, at least it looks like this. Any clues where to look at and find the issue with the liveliness check ?
