Java process removed: 1388@MAPLM

I receive three emails every morning at 4:17 AM.  First one states that the method server stopping, message is "JMX connection to method server
'BackgroundMethodServer.1388' failed".  The second one states the "Method server 'BackgroundMethodServer.1388' removed" and third one Servlet Engine Stopped:  Java process removed: 1388@MAPLM.  How do I go about troubleshooting?  This just started about ten days ago when the windchill server was rebooted.

Thanks for any info you can provide!
