I have never used that kind of switch. From what you have shown it sounds like a bug. Try updating the firmware. Maybe that will fix it. A new one just came out on 12/2/14. If this doesn't help try doing a small amount, like 6 ports at a time to see if you can. And increase it by like two each time to see if your theory about their being too many is right. Then contact tech support and see if they have fix.
I hope that helps.
Thanks deltranathaniel. This is a production switch so I'm a little hesitant to upgrade the firmware. When I said its uptime was 3 days I failed to mention that it had been up for at least 6 months before that, so this isn't a new switch I'm trying to configure. I may have one available in a week or so that I can experiment with. The number of ports definitely seems to have an effect, but I also believe it's the way they are specified.
"int range gig 0/1-48" works every time. "int gig range 0/1,0/2,...,0/48" would almost surely fail.
The range command is awesome when it works. Can reduce hours of Web Interface drudgery to just a few minutes of work.
