I had Plone running locally on 8080

I started <pre>fossil ui</pre> and instead of 8081 port, 8080 has been used. Plone has been replaced by fossil web interface.

There is no message displayed. I expected
<pre>Listening for HTTP requests on TCP port 8080</pre>

I started i other source tree (other project) also <pre>fossil ui</pre> and I got properly 
<pre>Listening for HTTP requests on TCP port 8081</pre>

I'm using Mac OS X
