Maria Catherine Tan closed CONTINUUM-2371.

1. check if the agent is available by calling the ping method before proceeding with the call
to other methods
2. if the agent is not available, disable it.

>          Issue Type: Bug
>          Components: Distributed Builds
>    Affects Versions: 1.3.4 (Beta)
>            Reporter: Wendy Smoak

> When a build agent goes down unexpectedly, the system does not handle it gracefully.
> The Queues page (/displayQueues!display.action) shows Error Occurred org.apache.maven.continuum.ContinuumException:
Error retrieving projects currently preparing build in http://localhost:8181/continuum-buildagent/xmlrpc

> To reproduce, add 2 or more agents, force a bunch of builds, then stop one of the agents
without disabling it from the master.
> I notice  that the Build Agents page (/buildAgentList.action) still shows the agent as
Enabled=true, even though it is not responding.
> There should probably be some concept of the system automatically disabling an agent
that is not behaving correctly.  For now I'd be happy with the admin having to manually re-enable
it, but an auto-recovery feature might be a nice enhancement for later.
