Some info columns not working

Some of my info pages aren't coming up. Just get Internal Server Error and Apache logs a "Premature end of script headers: bb-hostsvc.sh" when I try to access them. At first I thought maybe it was just the systems relayed through bbproxy, but I've found some tested locally from the main display server that also don't work, and there are relayed systems that DO have info. Checked all the hobbit logs and don't see any problems reported. Any troubleshooting tips?
