I do not know if Mapproxy is already utilizing thishttp://www.sqlite.org/wal.html
If not it feels like your use case would be something that could have use for WAL. Let's wait what the developers say.

what is the best option for keeping a cache of a layer in the filesystem?
I've used sqlite because of the benefits of the database (vs filesystem) and the ability to use refresh_before seeds..
But when seeding, I keep running into the following fatal error: sqlite3.OperationalError: database is locked
Is there anything I could do here? Is is because of the concurrency of the seeding (and the on-the-fly rendering) ?
While the file cache fills up my inodes very fast, I don't have these locking problems..
What's the ideal solution for a layer that has to be reseeded once a week but continuously online?
