Good point:

mongrel_cluster.yml
-------------------
user: dwayne
cwd: /var/www/apps/central/current
port: "8000"
environment: production
group: mongrel
address: 127.0.0.1
pid_file: log/mongrel.pid
servers: 3
-------------------

Commenting out the pid_file line makes no difference. Still the same  
issue.
