Crowd installation error

Question

I was trying to install crowd. I am not able to install it as it doesn't initiate the process ( I cannot open http://crowd.mydomain.com:8095/crowd ), it gives me a blank screen.

Here is the log from /var/crowd-home/atlassian-crowd.log

Answer 1

I had exactly same problem and reason was that there was already a running instance. Just shut it down and restart.
