Description

When a large (1.5MB) file is attached to a Wiki page, the upload sometimes ends up with the following error:

Operational error: Database is locked

I attempt to upload the file against a tracd standalone server (being the only user, performing a single HTTP request at a time), and against Apache 2.0.53 + mod_python.

tracd dumps the following traces on std output while the file is being uploaded (or before any byte transfer ?)

The "database is locked" error should be much less frequent now.
