Re: [mapserver-users] MapCache - failed to remove lockfile error
Thomas, The latest version (as of last week) seems to have fixed the lockfile issue. We are running into issues with the linking of transparent tiles: failed to link tile /home/caches/0837DURH_cache/googlemaps_grid/21/000/590/400/001/333/608.xxx to /home/caches/0837DURH_cache/googlemaps_grid/blanks/.xxx: No such file or directory We are running the seeder with 24 threads (all cores on the server). Could there be a issue with linking to the same file simultaneously?
