The dirty priority<br>is a background priority in which mod_tile does not wait for the result and<br>immediately returns the tile (or in case of a missing tile a 404).<br></blockquote><div><br></div><div>This is indeed the case, but sometimes - in these seldom cases when rendering on the first request works - the "command RenderPrio" instead of "command Dirty" appears in /var/log/syslog (see below). Does that indicate that it might by a load-related decision from mod_tile?</div><div><br></div><blockquote type="cite">So the question is why does mod_tile send the requests with the incorrect<br>priority? This should only happen if the load average is above the<br>configured max missing load. Your configurations do look fine though.<br></blockquote><div><br></div><div>Do you know by chance what unit "ModTileMaxLoadMissing" uses? Is it a percentage? The settings for the log below were as follows:</div><div><br></div><div><div>ModTileRequestTimeout 900</div><div>ModTileMissingRequestTimeout 300</div><div>ModTileMaxLoadMissing 500</div></div><br><blockquote type="cite">Can you increase the debug level of mod_tile to debug and then post your<br>apache error.log again? The debug output unfortunately currently doesn't<br>tell you what mod_tile thinks the load on the server is, but at least it<br>would confirm if this is the cause and what the configuration is set to.<br></blockquote><div><br></div><div>In /etc/apache2/site-available/default I changed the log-value by changing the line to "LogLevel debug". Is there any other way to increase the debug level of mod_tile?</div><div><br></div>Greetings, Stefan</div><div><br></div><div>/var/log/syslog</div><div>-------------</div><div>Nov 9 20:15:44 xxxxxx
