Here's a uncommon situation in our current mailserver... Load below 1.0....

 12:51:33  up 2 days, 23:27,  1 user,  load average: 0.27, 0.19, 0.09
101 processes: 100 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:   3.8% user   0.9% system   0.0% nice  11.4% iowait  83.7% idle
Mem:  1035084k av, 1006372k used,   28712k free,       0k shrd,   68100k 
buff
       699292k active,             273556k inactive
Swap: 2008084k av,       0k used, 2008084k free                  785108k 
cached

We tried to add more 512Mb but the RAM is too close to the CPU and it 
got too hot and the system locked...

I study at UFMG.... good university , but hard as hell... If I gave the 
orders , all linux machines would be running fedora right now at DCC ,
but I dont , so someone chose Suse.... So all fedora machines are 
probably going to be reinstalled with suse someday... :(
Btw , probably you asked in english because you thought about the others 
in the list... ;)

inteh....
