I'm really thinking it's either running out of memory and swapping/running out of disk bandwidth. causing wait states
check out load with top and see where the load is.....I can pretty much bet the cpus are spending most of their times in wait states

Thanks for your interesting and post Steve.
Actually, the computer have just one physical processor but the kernel is recognizing two processors (ACPI/APM?). The kernel is compiled with SMP support. But iīm not sure if the system is using the two processors. I donīt know if this is the cause of my problem.
About memory questions, see below:
root@slack:~# free -m
total used free shared buffers cached
Mem: 2016 1821 194 0 97 1514
-/+ buffers/cache: 209 1806
Swap: 494 2 491

To explain you better whatīs going on, letīs take this scenario.
Four people on talking on telephone. Then, two hangup and the soxmix/lame starts the convertion of wav to mp3. The other two have their call prejudicated, because the process os soxmix/lame are consuming much CPU.
I donīt know if I was clear, but looks like an "interruption" or "priority" to use the processor.
On Suse 9.2/10.0/10.2/10.3 we donīt have this kind of problem.
I hope it helps.
Thanks again
