body: <p>While running some experimental Java code which interacts with a MySQL server, I received these messages and then the server crashed:</p>

  <p>What do they mean? After restart, everything is working again. /var/log/messages has no entries near the time of the event and dmesg doesn't seem to show anything about it either. </p>
