JDBC error

I have a Java app that connects to a MS SQL Server using JDBC.  It reads
the requests from a data queue and writes the result set to a second
data queue.  This has been working for some time.  

I received a call this morning from a user saying that it crashed with
an error (see below).  A quick check revealed that the SQL Server had
been changed.  The server went from "//ip address\\beforename" to "//ip
address\\aftername".  I changed the program that writes to the data
queue but it still kept returning the same error.  The server admin
recreated the old server and the program worked.  I have debugged the
Java app and I know that it is using the new server.

Does the iSeries do some type connection sharing where it keeps using
the same (wrong) connection?
