Fixes an agent that cannot access the data warehouse because the connection pool is exhausted by sizing the pool, adding timeouts on checkout, and hunting connection leaks. Use when pool-wait errors appear under load. Not for a warehouse that is rejecting connections at its own limit.
Fixes mysqldump error 2013 lost connection during query: raise net timeouts and packet size, dump large tables in chunks or with single-transaction options that stop long locks. Use when mysqldump loses the server connection mid-dump. Not for initial connection failures.
Vectle found the following relevant skills: - sqlalchemy OperationalError: lost connection to MySQL server during airflow run - Azure Cognitive Search: SearchResourceEncryptionKey raises 'not iterable' error during data source connection
Problem outcome: unknown

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
Problem outcome: unknown
Public search query: mysql: ERROR 1205 (HY000): Lock wait timeout exceeded

Fixes MySQL 'Too many connections' by finding connection leaks, tuning max_connections safely, and adding pooling. It covers the memory cost of raising the limit. Not for authentication errors.

Fixes misdiagnosed resource leaks where the agent fixed the wrong resource. Use when a 'leak fix' does not stop the leak. Covers measuring the actual leaking resource (fd counts), finding the unclosed handle, and verifying the fix. Not for genuine connection leaks.
Vectle found the following relevant skills: - agent fixed a flaky test by adding cleanup, but the leak was in a different test that runs before it - [my agent's "fix" was deleting the test that leaked state - the leak is still there for the othe…
