Last Modified: Jun 28, 2025

Affected Product(s):
BIG-IP DNS, GTM, LTM(all modules)

Known Affected Versions:
16.1.5, 16.1.5.1, 16.1.5.2, 16.1.6, 17.1.2, 17.1.2.1, 17.1.2.2, 17.5.0, 17.5.1

Opened: May 21, 2025

Severity: 4-Minor

Symptoms

A database monitor (mssql, mysql, oracle, postgresql) may send multiple queries to the database server in quick succession if the monitor is configured with a 'recv' string, but the response from the server does not contain the configured string.

Impact

The database monitor correctly marks the configured pool member 'DOWN' as appropriate, but generates unnecessary queries to the database server.

Conditions

-- A database monitor (mssql, mysql, oracle, postgresql) is configured with a 'recv' string. -- The query to the database server completes successfully, but the response does not contain the configured 'recv' string.
