I've waited to contact them, I wanted to be sure I wasn't running into an config or Orion issue first. I'm also going to reboot the switch asap (not really an option during business hours).
IOS Version is 15.0(2)SE
The only possibly relevant bug I could find was related to SNMP traps, rather than polls.
Sooo, rebooting didn't resolve the issue. I've sniffed traffic between the switch and the Orion server and I couldn't find any SNMP packet with a bad community string. I'll be contacting our vendor, thanks to everyone for the help.
