"./OpenGrok index" failed

Question

I am trying to implement OpenGrok to search some source tree. There was no error when running "./OpenGrok deploy", but afterwards when I ran "./OpenGrok index", there jumped lots of similar errors which I will attached below. The full source tree I want to search is a very hug project, around 20G big, and the weird thing is that, I can successfully run "./OpenGrok index" if the source code is a small size one. So I am not sure is there any file number limit or size limit that OpenGrok follows, if there is, where can I make changes? Or it is because some other reason.

Thanks!

Do you Do the openGrok index while checking out the code , and from error code. Have you put cvs to your env path
