Sharepoint Central Administration v4 terminated unexpectedly

Our SharePoint farm had been up an running for a about month. We recently rebooted the system could no longer connect to the Central Administration website (503 error). The server is a 2008 R2 and we have verified that the Pool is using v2.0 .net and the correct farm account. The security log does not show anything being denied. The pool seems to continue running, but the Farm website is not available.  The following event logs are all we can attribute to the problem. Is there a way to get more detailed information on why the process is terminating unexpectedly?
