Job tracker timeout error

[Jason Camp <jc...@vhosting.com>]

I've seen this a few times, I'm getting a timeout error on the job 
tracker for just one of the task trackers - the messages from the logs 
are below. The task tracker does get the job and finishes processing it, 
but from what I can tell the job tracker doesn't use it. Any idea where 
the error comes from, and if there's something i need to adjust? Thanks!
