Overview

Raised when the database lock could not be taken inside the adapter's wait budget (PRAGMA busy_timeout, 5 s on SQLite). The unit did not commit, so the caller may retry the whole unit; retrying one statement inside an open transaction is not safe, because the driver may have already rolled that transaction back.

Both adapters map their lock errors here: the sqlite adapter its driver codes 5 (SQLITE_BUSY) and 6 (SQLITE_LOCKED), the PostgreSQL adapter the SQLSTATEs 40P01 (deadlock detected), 55P03 (lock not available) and 40001 (serialization failure).
