enough big number of jvms. Is your server based on 8 cores with 16 or
32GB ? I would say you should have a big enough swap as well for all
these JVMs and the needed reservations.
We were in a T2000, 8 cores, 32GB RAM with 4 zones, 20-25 jvms. It is

Read this: vs. number of cores :=)
We had a kind of similar problem at our office where we simple had too many
java app server instances running on one T2000 box. Hard things comes to
size properly a T2000, how one should do tha

Hi,
when you run your Perl scripts what 'vmstat 1' shows ? As well what exactly are
those perl scripts, are you monitoring your site using them or ?
Couple of other questions:

Hi,

top reports 16G main memory, 800m free
There are several zones running, containin
