      Description

      With the 1.8.5 Zabbix agent, some of our hosts show 0% idle CPU on Zabbix while vmstat and top report >0% idle.
      Downgrading to the 1.8.4 agent makes the problem go away.

      This only seems to be a problem on hosts with non-contiguous CPU IDs, e.g.:

      OK:

      $ psrinfo

      1 on-line since 12/01/2009 19:19:50

      Not OK:

      $ psrinfo
