Hi Guys, I'm having an issues just at once that my HA Agent stops running and can't be restarted or won't start anymore after the following error. I'm able to start the HE manually on the commandline on each host. Exception: Failed to start monitoring domain (sd_uuid=4093ad17-bef5-4e4b-9a16-259a98e20321, host_id=1): timeout during domain acquisition MainThread::WARNING::2016-07-22 13:20:05,059::hosted_engine::477::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:: (start_monitoring) Error while monitoring engine: Failed to start monitoring domain (sd_uuid=4093ad17-bef5-4e4b-9a16-259a98e20321, host_id=1): timeout during domain acquisition MainThread::WARNING::2016-07-22 13:20:05,059::hosted_engine::480::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:: (start_monitoring) Unexpected error Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 451, in start_monitoring self._initialize_domain_monitor() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/agent/hosted_engine.py", line 831, in _initialize_domain_monitor raise Exception(msg) Exception: Failed to start monitoring domain (sd_uuid=4093ad17-bef5-4e4b-9a16-259a98e20321, host_id=1): timeout during domain acquisition MainThread::ERROR::2016-07-22 13:20:05,060::hosted_engine::493::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:: (start_monitoring) Shutting down the agent because of 3 failures in a row!

Thanks! Matt
