HP wrote a script, which I previously posted to this venue, to modify the keepalive parameters (on an HP platform) to poll the socket for a dead client and then close the socket connection. The script modifies the running kernel to set these parameters. I will supply it upon request, but with the caveat that if you're running other than an HP 9000 with HP/UX 7.x, 8.x, or 9.x that you consult your OS tech support before attempting to implement it. ___ ___ Senior Consultant / ) __ . __/ /_ ) _ _ __ Informix Software Inc.
