Hi Vipin,
The log file comes out to be clean. However I have 2 questions -When you start your instance I am sure apache log will say something for ex: clicking on the page, selecting tool etc. I am sure about that.1. Which version are you using to run your test instance?The recent one, but it is quite sure that the tool integration in quite stable from past couple of months.2. Did you make any changes to your Python execution environment for Galaxy?From the error it seems that it is not problem with Python environment set-up.Please let me know.
How is going with your Galaxy tool integration, I was away for the last couple of days.
Hope things are worked at your end.
