>Description:

On FreeBSD 7.1 with the ULE scheduler, bsnmpd always returns 100% CPU
utilization.

There was a thread about this here:

http://kerneltrap.org/mailarchive/freebsd-current/2008/5/7/1747854/thread

but the problem still occurs.

>How-To-Repeat:

Enable and start bsnmpd, and enable the HOST-RESOURCES-MIB in
snmpd.config

Then:

aphrodite:/etc$ snmpwalk -v2c -c public localhost|grep hrProcessorLoad
HOST-RESOURCES-MIB::hrProcessorLoad.7 = INTEGER: 100
