#3446: Rate of database is locked errors is too high (see all) This used to be a plague with the SQLite database backend, but it seems that things improved over time and this once #1 duplicate bug is less frequent those days. The problem should even be completely gone with 0.11.6 or 0.12dev. A more scary variant of #3446 is #4929, where the lock situation seems to persist and needs a server restart (rare).

Yes, this is a duplicate of #3446.
