We test limited number RPZ list BIND 9.8.1 (came with Ubuntu 12.04), and
put it on the live network, the result is OK, all load is shared among
24 CPU, @10% usage
Then in response to BIND Security Advisory (exploit), we upgraded it to
9.8.5-P2, and we increase to RPZ list to a huge list (1,3M blacklist)
But now the CPU load is seem to focus only on CPU0 (40%), and remaining
CPU (1-23) only around 2%
Any idea what may seems to be the problem,
Did you build the 9.8.5-P2 binaries yourself from ISC source or do you
know what configure options were used? (If you're not sure, you can
check by running named -V)
You might check to make sure that threads are enabled, or enable them
explicitly with "./configure --enable-threads" (+whatever other options
you built with previously) before re-building the source.
