誰か教えてください。

sakuravps centos

yum updateするとsendmailが・・・というかcyrus-sasl周りがエラー吐く。
調べてみるとなぜかi386がinstallされている。(x86_64も入っているが)

さらに調べてみるとi386のパッケージが94個も発見された。
これはCentOSの最小構成でも入るものなのか？
それともsakura vpsが何か事情があっていれてるものなのか？

まず、CentOSに起因するのか、sakura vpsに起因するのかが知りたい。
そして何故そうなっているのかも気になる。

だれか教えてください。

以下入ってるi386パッケージ(rpm remove '*.i386'で確認)
