The backend processes do the actual rendering of tiles. .PP The backend manager expects each worker process to send an \*(L"alive\*(R" message in regular intervals, and will kill the process if it does not do so in time. .PP The backend manager does not handle render requests in any way; these are read directly from a local \s-1UDP\s0 socket by the individual backend processes. .PP If the backend manager receives a \s-1HUP\s0 signal, it will relay this signal to all backends, causing them to exit after completing their current request. It will reload the renderer and map configuration and re-start all workers with the new configuration. .SH "FILES" .IX Header "FILES" .IP "\fI/etc/tirex/tirex.conf\fR" 4 .IX Item "/etc/tirex/tirex.conf" The configuration file. .IP "\fI/etc/tirex/renderer/*.conf\fR" 4 .IX Item "/etc/tirex/renderer/*.conf" Configuration files for renderers .IP "\fI/etc/tirex/renderer/*/*.conf\fR" 4 .IX Item "/etc/tirex/renderer/*/*.conf" Map configurations .SH "DIAGNOSTICS" .IX Header "DIAGNOSTICS" The backend manager logs to the \fIdaemon\fR syslog facility unless configured otherwise.
