Must have been a screen refresh issue. Here is another sample from TOP.
Does anyone know what the commands Jeff spoke about would be in Linux.
Thanks
Jay

Jason,
Your CPU states show 2 cpus at 0% which suggests you may ne be getting an
accurate picture of your system's performance, in top or snmp.
I have JFFNMS running on on an aging dual cpu Ultra2 which consistantly has
a load of about 6.0, 3.0, 3.0 but averages 65% idle. The machine is a little
sluggish when the poller is running due to system paging but other than that
, still fairly responsive for a 10 y/o machine running as my desktop.
You may want to check some other system utilities to see if you have paging
issues, disk i/o problems, blocked i/o, network issues, etc. I'm not sure
what the equivelant commands are on linux but in Solaris they would be
vmstat, mpstat, iostat, netstat for example.
