I'm using 11.10 64-bit desktop and I have apache installed for a personal site. I'm experiencing a very strange behavior. When i startup apache my site works great for about an hour or so, but then when I try to access it after that point I get cannot load page and server not responding. I can ping my site from my laptop. I have checked the error logs and there is nothing showing up at the time the server stops responding. Oddly enough though when I surf the internet on the desktop I noticed that my site started to function normally again. Once i stop surfing the internet the server will function normally for about another hour or so then stop responding, again with no error messages in the log file. Restarting apache does not work but restarting the desktop does. I am at a loss as to what could be causing this behavior.
