A public API returns a new discussion identifier before a background worker finishes computing its recommendations. The worker updates only derived context and recommendation rows, but it holds an exclusive lock on the public discussion while performing a second candidate scan. A normal read requests a shared lock and…

Vectle found the following relevant skills: - Additive Postgres migration release gate - agent added a column with a default to a 500M-row table and postgres is rewriting the whole table while the app is live
Vectle found the following relevant skills: - Active Directory provisioning failed LDAP error 19 "constraint violation, password does not meet complexity... - [agent hallucinating data quality rules failure invented non-existent constraints erro…
Describes how to fix a Barman backup failing with WAL archive timeout by checking the archive path from Postgres to Barman, the receive-wal process, archiver statistics and space on the Barman server. Use when barman check or a backup waits on WAL archiving. Not for a pg_dump logical backup failure.
Fixes MySQL 1205 lock-wait timeouts by finding the blocking transaction, killing or fixing it, and shortening transaction scope with proper indexes. Not for deadlocks.
Vectle found the following relevant skills: - mysql error: Lock wait timeout exceeded - try restarting transaction - how to find the blocker - jest "thrown: Exceeded timeout" with no stack trace in CI logs: how to get the real error
Fixes Postgres serialization failures under serializable isolation by adding application-level retries with backoff. It covers reducing contention as the long-term fix. Not for deadlock errors.
Fixes warehouse deadlocks during dbt runs for analytics engineers and repair agents. Use when the database reports a deadlock while dbt models build. Not for statement timeouts or lock waits that eventually clear.
Vectle found the following relevant skills: - Database Error: permission denied for table on dbt run - psycopg2 error DeadlockDetected: deadlock detected during concurrent migration
Response playbook for an ALTER TABLE that ran 6 hours blocking deploys because no statement_timeout was set: stopping it safely, setting timeouts, and using online schema-change tools instead. Use when a DDL statement runs unbounded and blocks everything behind it. Not for slow DML or stuck queries.
How to fix a deploy marked failed because the health check queried a table the migration had locked: making health checks lock-aware and migration-safe. Use when health checks fail spuriously during migrations. Not for health checks failing because the app is genuinely broken.
How to fix gh-ost's "FATAL cannot acquire lock on table" during an online schema migration: finding the blocking workload, retrying the cutover in a quiet window, and tuning the lock settings. Use when gh-ost fails at the cutover step because it cannot get the brief table lock it needs. Not for failures during the row…
