Dear all,

I found a big problem with my solaris9 server when user said their application run too slow then I try to check cpu, memory but both of them are normally. One thing that I see form value of vmstat like this

 kthr      memory            page            disk          faults      cpu
 r b w   swap  free  re  mf pi po fr de sr s0 s3 s4 s1   in   sy   cs us sy id
 0 0 70 41868264 1168696 421 2568 179 17 20 0 24 0 0 0 0 1951 2219 4557 6 2 93

The high w numbers aren't the cause but the consequence of a previous strong RAM shortage. These are processes completely swapped out. No big deal as they aren't doing anything anyway.

Dear jlliagre,

Thank you for your reply
