Looks like the mongrel_rails command in mongrel 1.1 still
does not fix
(or include an option) the issue of stale pid files.
mongrel_rails
will just exit if a pid exists without first checking if
anything is
actually running. You can use this script to patch up
mongrel_rails...
#===== patch mongrel
cd /usr/lib/ruby/gems/1.8/gems/mongrel-1.1/bin/
cp mongrel_rails mongrel_rails.orig
patch -p0 << 'EOF'

if File.exist? defaults[:pid_file]

+ exit 1
+ else
+ log "!!! PID file
#{defaults[:pid_file]} exists, but

run."

end
