First your ServerName is wrong, check the documentation to find out why.
Second, are both backend servers identical in configuration? And what are
they actually? The Jakarta in the error makes me think they are Tomcats

And third, why dont you check the error and access log on the second server
and make sure the server is running fine and is really not getting the
requests before you post back here?
