New Description:

The problem here is that I've defined Event tracking on the agent.log. Also, I've defined an alert def on ERROR events.  The agent is suffering from the following types of errors:

2008-05-05 13:42:56,686 ERROR [ClientCommandSenderTask Timer Thread #1] (enterprise.communications.command.client.JBossRemotingRemoteCommunicator)- {JBossRemotingRemoteCommunicator.comm-cce}The remote server did not reply with a valid command response. Reply was: CORRUPT org.rhq.enterprise.communications.command.impl.remotepojo.RemotePojoInvocationCommandResponse CORRUPT rg.rhq.enterprise.communications.command.AbstractCommandResponse CORRUPT

With the null bytes removed for readability (notepad does this) :

When the log message is communicated as the event text it fails to be stored in the db due to its corrupted nature:

So, two problems here, corrupted agent data and the inability to handle events with bad/null chars in the log.
