You may be right. You might end up with fewer page requests. I'm not real up on VM, but I know that smaller memory will help. The other thought is that there is less applications in memory so fewer chances to segfault or come across any other bugs. I didn't start trimming down the loaded modules till the report of the long fixed sip bug. > --- TeleSIP <[EMAIL PROTECTED]> wrote: > > > > > Another trick to look into is cutting down of the asterisk modules > > that > > > are loaded.
