Subject agent host in alert state
Date Mon, 26 Jan 2015 15:05:05 GMT
Hi all,
we have installed a cloudstack 4.3.0 in advanced network mode on ubuntu 
systems with only kvm hypervisor.

Today we received these series of notification (email):
  1) Host disconnected, name: agent_name (id:7), availability zone: 
zone_name, pod: pod_name
  2) Host is down, name: agent_name (id:7), availability zone: 
zone_name, pod: pod_name
  3) Host disconnected, name: agent_name (id:7), availability zone: 
zone_name, pod: pod_name
  4) Host is down, name: agent_name (id:7), availability zone: 
zone_name, pod: pod_name
  5) Unable to restart vm_name which was running on host name: 
agent_name(id:7), availability zone: zone_name, pod: pod_name

The server agent was not shut down nor rebooted and the virtual machines 
are still running.

In agent log I found messages like these:

2015-01-26 15:04:40,728 INFO  [cloud.agent.Agent] (Agent-Handler-2:null) 
Cannot connect because we still have 5 commands in progress.
2015-01-26 15:04:45,729 INFO  [cloud.agent.Agent] (Agent-Handler-2:null) 
Lost connection to the server. Dealing with the remaining commands...
2015-01-26 15:04:45,729 INFO  [cloud.agent.Agent] (Agent-Handler-2:null)

2015-01-26 15:04:50,729 INFO  [cloud.agent.Agent] (Agent-Handler-2:null) 
Lost connection to the server. Dealing with the remaining commands...


I tried to restart the agent service and after some minutes the log says:

2015-01-26 15:05:42,207 INFO  [utils.nio.NioClient] 
(Agent-Selector:null) Connecting to manager_ip:8250
2015-01-26 15:05:42,489 INFO  [utils.nio.NioClient] 
(Agent-Selector:null) SSL: Handshake done
2015-01-26 15:05:42,489 INFO  [utils.nio.NioClient] 
(Agent-Selector:null) Connected to manager_ip:8250

But in manager interface I see this agent in Alert state.

Any idea to resolve this problem?
