tilecache_seed dies at a specific tile - how can I skip it?

Hello everyone,
I'm getting an error while trying to cache offline parts of my map. The caching process runs fine until it hits a particular tile (my guess is it's tile 9143) - when the process dies (after a timeout of 2 minutes). Here are samples of the output: [root@terra utilities]# python /var/www/html/tilecache/tilecache_seed.py rtc_base 1 10 --bbox 2255332.8831578,5336357.2739115,3306188.8761,6183726.4985628 ... 07 (004621, 005229) = (2568284.1491 5542601.7932 2573176.1189 5547493.7630) [0.0003s : 2391.549/s] 9137/37195 07 (004622, 005229) = (2573176.1189 5542601.7932 2578068.0887 5547493.7630) [0.0003s : 2391.566/s] 9138/37195 07 (004623, 005229) = (2578068.0887 5542601.7932 2582960.0586 5547493.7630) [0.0003s : 2391.586/s] 9139/37195 07 (004624, 005229) = (2582960.0586 5542601.7932 2587852.0284 5547493.7630) [0.0003s : 2391.606/s] 9140/37195 07 (004625, 005229) = (2587852.0284 5542601.7932 2592743.9982 5547493.7630) [0.0003s : 2391.624/s] 9141/37195 07 (004626, 005229) = (2592743.9982 5542601.7932 2597635.9680 5547493.7630) [0.0003s : 2391.643/s] 9142/37195 Traceback (most recent call last): File "/var/www/html/tilecache/tilecache_seed.py", line 9, in ?

I'm not sure how it works on Linux, but on Windows, the URL is mapserv.exe (your link it appears to be just mapserv).

Look in the apache logs for the mapserver, look at what the URL is, and send it to the mapserver. See if it fails in the same way. If so, it's a mapserver 'issue' (quotes because it may simply be taking too long to do this tile, and the actual issue is that you need to bump up your apache timeout), and can be treated externally to TileCache. -- Chris > > Thanks, > Adrian > > _______________________________________________ > Tilecache mailing list > [hidden email] > http://openlayers.org/mailman/listinfo/tilecache -- Christopher Schmidt MetaCarta _______________________________________________ Tilecache mailing list [hidden email] http://openlayers.org/mailman/listinfo/tilecache |

Thanks for the help,Unfortunately I am not a python programmer (perl is my thing), but I will *try* to have a look in the source code, or try to catch the url from apache (unfortunately the server is in production and has lots of requests)...
