It isn't launched 7 times. Asterisk is a multi-threaded application and 
depending on what modules are active, a new thread will be created. That's 
what you see.
The line 'asterisk -vvvg -c' doesn't mean that every thread has it's own
'c'onsole. Just one thread is the console.
So this is absolutly normal.
When, on some systems, do just see one thread/program, then this system just 
show the main-thread. This depends on kernel/ps version.
