Affected Product:  See more info
BIG-IP LTM(all modules)

Known Affected Versions:
15.0.0, 15.0.1

Opened: May 01, 2019
Severity: 3-Major


When the server connection fails to be established due to server being down or actively rejecting the connection, LB_FAILED should fire and allow a new destination to be selected via iRule.


Selection of a new destination via LB_FAILED is not possible, thus the client connection will be aborted.


- iRule with LB_FAILED event - server connection establishment fails


No workaround available.
