Not sure what is going on here, what about your other hosted webpage? I'm curious about how you are hosting that and Airtime together. What happens when you do "service apache2 restart"?
Too many apache processes you mean? I'm running Squeeze as well and have the same amount of Apache processes running, but they are all near 0% CPU usage so they don't show up in "top". Do you have many users or many browsers open using Airtime?
You can check what is making requests to your server (and creating high CPU usage) by looking in:
In the end of that log, airtime-check-system runs and connects to "http://localhost:80" to get Airtime service status. Please verify that Airtime is code is responding to http://localhost requests.
I think there might be a conflict with your other Apache vhost file.
Thanks for your help, it's fixed , i don't know how, i have just reinstalled airtime and postgresql and everything looks fine, i just can't rebroacast a stream, i don't know if i need icecast to be installed
