Until some times ago, I was used to test with 32 bit centos, and I've
not seen problems (I tested with centos5.2).

Now I'm installing 5.3 32 bit, and I'll report on my results

On 64bit, on both centos5.2 and 5.3 I'm seeing problems with more than
6-10 concurrent calls, with less calls it was ok. BTW, it can be it is
a problem with my hard disk (that is seen as an ide instead than as a
SATA). I will check this too.

I'll report back soon on the various issues...
