Weird Problem

At the moment I'm having something strange happen on my mac,I recently switched ISP's and since then ive noticed the occasional dc, but one thing I found really odd was in my applications folder it keeps generating a file called upnp_trace.log, it makes 5 total then no more, if i delete them another 5 randomly appear a few days later after the odd dc has happened. Each files is 15kb in size and looking through they all seem to be identical jargon of some kind. Can anyone help?

Did you install any software from your new ISP on your machine? Are you running any network utilities? Look in your Login items and startup folder.

I didnt install anything, I just had to sign up for the new ISP and it switched over. I looked in my startup folder and login items and there's nothing unusual there, I could post the entire log's worth of info if that would help?

Something is generating that log, and for it to be showing up in your Applications folder is even more unusual.

Just thought of something... Do you have Vuze installed?

See this LINK. Maybe it's the reason that log is being generated. Let me know.

Ye I have Vuze installed so there's a good chance its related to that and harmless I guess, thanks for the help
