Named and load

Hey, I've been having some load spikes recently, and I just noticed in the log that 1 second after every spike, the following appears:

Mar 23 14:46:06 cp named[1570]: Cleaned cache of 364 RRsets
Mar 23 14:46:08 cp proftpd[22340]: cp.neoservers.com (208.185.248.240[208.185.248.240]) - FTP session closed.
Mar 23 14:46:07 cp named[1570]: USAGE 1080081967 1079919976 CPU=23.9u/9.04s CHILDCPU=0u/0s

Seeing as I'm not a bind expert, I'm not following what that is saying. Anybody have any idea? Thanks.

Edit: upon starting named, I get some errors about the root records.

Mar 23 15:10:16 cp named[27481]: check_hints: A records for B.ROOT-SERVERS.NET class 1 do not match hint records
Mar 23 15:10:17 cp su(pam_unix)[27523]: session closed for user postgres
Mar 23 15:10:20 cp named[27481]: check_hints: A records for J.ROOT-SERVERS.NET class 1 do not match hint records

That linked to this other issue somehow?
