Redmine

Hello,

I'm trying to install multiple redmine on the same server, it's on iis 7.

I duplicated the first redmine installed and placed it in an another directory. The twa works correctly but sometimes one or both of the site goes slow and return error message like this:

"The page cannot be displayed because the client took too long to complete its request and the server closed the connection."

Is there a way to make 2 instances of redmine works correctly on the same server? I think i made something wrong but don't know what.

Thank you.
