Forum: Mongrel strage mongrel cluster

Hi,will appreciate any advice from ruby guru :

I found strange behavior on mongrel cluster. Below are my installation
details :
#ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]

#rails -v
Rails 2.3.5

I use mongrel cluster 1.0.5 on Debian lenny (5.0). Also got the same
problem in ubuntu 8 LTS, with similar config.

when running just mongrel , it works properly. But when I tried to use
mongrel cluster, when I run :

#sudo mongrel_rails cluster::configure -e production -p 8000 -N 3 -c
/home/public_html/redmine -a 0.0.0.1 --user www-data --group www-data

#sudo mongrel_rails cluster::start
starting port 8000
starting port 8001
starting port 8002

No error messages.
Then I checked with  netstat -tap, there were no mongrel listening on
800x.
and check with px aux | grep mongrel, also nothing.

seems that there were no mongrel process running. Any help?
