  This is incorrect. Asterisk is a multithreaded system but how the threads 
are handled by the OS  depends on the version of threads that is being used.
   For Linuxthreads (kernel 2.4), one would see a separate entry for each 
thread when executing 'ps aux'. For NPTL (linux 2.6) one does not see each 
thread as a separate entry. So the OP must tell us which kernel version he is 
using. Alternatively type

             getconf  GNU_LIBPTHREAD_VERSION

as root. For NPTL u should get something like

             NPTL 2.3.5

or suchlike.

If you are using NPTL and there is more than one entry for asterisk, then 
asterisk has spawned an extra process for some reason. If extra processes 
keep appearing then I would say that he has a bug or error somewhere and 
asterisk is  respawning that separate process.
