A StartupMessage whose options parameter contains an empty parameter name, such as \"-c=\", makes the ignore_startup_parameters list lookup loop forever. Because PgBouncer serves all clients from a single process, this saturates a CPU core and makes PgBouncer unresponsive to all clients until the process is restarted."}], "lastModified": "2026-10-16T21:17:18.340", "sourceIdentifier": "f86ef6dc-4d3a-42ad-8f28-e6d5547a5007"}
