Tracing sqlturbo processes back to client PC

To simplify security maintenance on Unix in an environment that handles about 50 changes a week, we do all security checking on Novell and stop application access there. Then, all users come in under the same ID, using Power Builder queries. Using Informix, all their processes on the server have a parent of the sqlexecd daemon, but once the connection is made, sqlexecd is out of the picture. netstat shows us all the PC connections that are active. Is there anyway to link the tcp/ip address of the client to the sqlturbo(s) that it owns? This would make it much easier to track the source and cause of runaway requests. Informix 5.03, Solaris 2.4 Thanks, Ray
