I'd welcome any details on this "stalled file descriptor" problem. Is there a bug filed with some details like logs, sysrq-t and maybe even tcpdumps? If there is an easy way to reproduce this behaviour, I can surely look into it and hopefully come up with some advise or fix. Thanks, Niels

i've increased the limit and then restarted agent and broker. status normalize, but then right now it went to "False" state again but still both having 2400 score. agent logs remains the same, with "ovirt-ha-agent dead but subsys locked" status. ha-broker logs below Thread-138::INFO::2014-10-31 17:24:22,981::listener::134::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(setup) Connection established Thread-138::INFO::2014-10-31 17:24:22,991::listener::184::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle) Connection closed Thread-139::INFO::2014-10-31 17:24:38,385::listener::134::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(setup) Connection established Thread-139::INFO::2014-10-31 17:24:38,395::listener::184::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle) Connection closed Thread-140::INFO::2014-10-31 17:24:53,816::listener::134::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(setup) Connection established Thread-140::INFO::2014-10-31 17:24:53,827::listener::184::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle) Connection closed Thread-141::INFO::2014-10-31 17:25:09,172::listener::134::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(setup) Connection established Thread-141::INFO::2014-10-31 17:25:09,182::listener::184::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle) Connection closed Thread-142::INFO::2014-10-31 17:25:24,551::listener::134::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(setup) Connection established Thread-142::INFO::2014-10-31 17:25:24,562::listener::184::ovirt_hosted_engine_ha.broker.listener.ConnectionHandler::(handle) Connection closed Thanks, Jaicel
