Unable to restart mongrel service


I have upgraded my Redmine installation for my ite using SVN. After that
i have restarted mongrel and it failed. It is never starting again.

I used this command – mongrel_rails start -d

The error reported is :–

!!! Path to log file not valid: log/mongrel.log
!!! PID file log/mongrel.pid does not exist. Not running?

The mongrel.log file and mongrel.pid file are present in :–


So, pid file do exist.

My port where mongrel is acting up is 3000.

I also used the exhaustive command –

mongrel_rails start -e production -p 3000 -d -l

It specifies the port and full path of pid and mongrel log. Still error
appears. Iam stuck now. Please advice. Thank you.
