Hi I have got 8 Sun x4100's and i have got the following on there Linux xxxxxx04 2.6.9-34.0.2.ELsmp #1 SMP Fri Jun 30 10:32:04 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux I have found an issue where every hour the load rises to 1 sits there for nearly an hour and then drops to 0 again (these boxes are not currently being used) Has anyone seen this before or know perhaps why this may happen? When the load is high there is nothing showing in a top that may suggest a reason. thanks
