Sometimes (2-3 times per week), my websites goes down, then I have to manually restart Apache. I use Windows Web Server 2008 and Apache. It looks like Apache just keeps restarting and restarting. The error seems to be 'Failure releasing the start mutex'. I have Googled this, but can't find why my server does like this. Does anyone have any idea? Would really appreciate some answers!! =) [Thu Mar 25 10:55:26 2010] [notice] Parent: child process exited with status 3221225477 -- Restarting.
