I suspect the problem is synchronous blocking TCP operation. Openser tries to send to first contact, then to second contact. As sending to first contact fails (probably with a TCP timeout of 3 seconds - check core book documentation for setting TCP timeouts) it takes 3 seconds until it sends the request on the second connection. regards klaus _______________________________________________ Users mailing list [email protected] http://lists.openser.org/cgi-bin/mailman/listinfo/users
