212 <h2>Search took too long and was terminated</h2>
214 Sorry, but your query resulted in a search that took too long.
215 Searches are limited to <% $maxcpu |h %> seconds of CPU time to
216 avoid them consuming excessive resources on the server system, and to
217 make sure that shorter searches can still happen.
220 Please try a search with a smaller minimum distance, or place more
221 restrictions on the route.
229 <h2>Server too busy</h2>
231 Sorry, but there are already <% $concur_lim |h %> route searches
232 running. We limit the number which can run at once to avoid
233 overloading the server system and to make sure that the rest of the
234 YARRG website still runs quickly.
237 If you submitted several searches and gave up on them (eg by hitting
238 `back' or `stop' in your browser), be aware that that doesn't
239 generally stop the search process at the server end. So it's best to
240 avoid asking for large searches that you're not sure about.
243 Otherwise, please try later. Searches are limited to <% $maxcpu |h %>
244 seconds of CPU time so more processing resources should be available soon.
