How to fix when you can't get agents to restart

So generally when you have an agent that wont restart 10 times, there is no way to get the agent to restart. Reboots, restarting to dispatcher etc: The only way to get it to restart is to go into the bes logs, and rename the bes logs, like OLD_BES_LOG. The way we were able to figure this out by looking at the BES log and seeing at the end of the log it would actually say END OF LOG.
