Description:
When agent in debug log-level, it does not log at all about the connection being lost to the server it is monitoring. Aborted connections were occurring, but this was not being logged by the agent, agent logs about trying to gain sync again only.
080528 13:59:15 [Warning] Aborted connection 23 to db: 'unconnected' user: 'root' host: 'localhost' (Got timeout reading communication packets)
See here the agent debug log, it appears everything is working fine, but the above aborted connection occurred.

How to repeat:
Above was repeated with low wait_timeout, causing connection to abort whilst in debug log level.
Suggested fix:
Log that connection to monitored server disconnected/reconnected/failed attempts etc.
