Eventually, the poor xmppdaemon has become overloaded with extra tasks. So, I've broken it up. Now, we have 5 background scripts, and more coming: * xmppdaemon.php - handles incoming XMPP messages only. * xmppqueuehandler.php - sends notices from the queue out through XMPP. * smsqueuehandler.php - sends notices from the queue out over SMS * ombqueuehandler.php - sends notices from the queue out over OMB * xmppconfirmhandler.php - sends confirmation requests out over XMPP. This is in addition to maildaemon.php, which takes incoming messages. None of these are "true" daemons -- they don't daemonize themselves automatically. Use nohup or another tool to background them. monit can also be useful to keep them running. At some point, these might become fork()'ing daemons, able to handle more than one notice at a time. For now, I'm just running multiple instances, hoping they don't interfere. darcs-hash:20080827205407-84dde-97884a12f5f4e54c93bc785bd280683d1ee7e749.gz
