It sounds like it's waiting for the reverse DNS lookup to time-out. For whatever reason, the iSeries PING will first do a "forward DNS lookup" to get the IP address of the host you want to send the ping to, and then it does a reverse lookup on that address to get back the name. For example, let's say I have an iSeries called "bigbertha.example.com" and I have "iSeries.example.com" set up as an alias for that. If I type: ping iseries.example.com it sends back a messae like this: Verifying connection to host system BIGBERTHA.EXAMPLE.COM at address 192.168.0.1. How did it know that "iseries.example.com" was also called "bigbertha"? Because it first got the address, then did a reverse-lookup on that address to get the "canonical" hostname. Okay, now that I've explained all of that... your problem sounds like the reverse DNS is waiting to time-out. On FreeBSD I can specify an option to tell it not to do DNS (which is useful in networks that don't have a DNS server) but the iSeries doesn't appear to have this feature.
