I installed web2py with this script on webfaction: http://wiki.webfaction.com/wiki/Web2py-LatestSource which uses "Python 2.5 along with Apache + mod_wsgi v2.5" > > The apache server is still running but the app won't work until I > > reset apache. > > These are the common errors from the Apache log: > > > server reached MaxClients setting, consider raising the MaxClients > > setting > > Which means Apache and/or mod_wsgi daemon mode isn't configured with > enough processes/threads to handle the concurrent load you are > getting. hmm, it's just me and I am not making concurrent requests.
