Zabbix 2.2.3が出て非常におめでたいことなのですが、2.2.3にアップグレードしたところ、自宅にあるRouterboardのSNMPから値が取得できなくなる事象に出会いました。
logには以下の様なメッセージが出力されるようになりました。

とりあえず現状ではZabbixを2.2.2へダウングレードすることで一旦は問題を回避することにしました。
yum downgrade zabbix*原因の究明方法をご存じの方は是非ともご教示ください。
Twitterで呟いたところ、以下のアドバイスを頂きました。
@kometchtech バルクゲットの部分で、mib読み込む部分がうまく実装されてないのかな。

@kometchtech @qryuu そのbulk requestのリクエストの内容がRBが理解できるような内容でなかったりするのではないかと疑っています。
