Newbie - mongrel cluster issue

Hi ,

I am a newbie to RoR. When I start mongrel_rails , I can access my app. on http://localhost:3000 fine. However, when I start the mongrelcluster,
I cannot access it on http://localhost:3001 (which is what ideally be the case?). I don’t see any errors in the logs as well:

/opt/blog/log]# ps -aef|grep mong

/opt/blog/log]# tail -f mongrel.3001.log
** TERM signal received.
