I saw a resembling thing here after upgrading to 10-stable yesterday. I noticed bsnmp running at 30 to 40% cpu continuously, resembling what I found here: https://forums.freebsd.org/threads/37045/ After ktrace-ing the process I noticed it was doing sysctl stuff all the time and a more close look showed that it was freaking out on the CD device without a medium. So I inserted a CD in the device, and bsnmp went back to normal. "Interesting". So far I didn't notice memory issues.
