Error description
Edge Load Balancer uLB TLS advisor timeout does not work as documented. The timeout value shown as unlimited on the advisor status report is misleading because it isn't the advisor timeout but is how long the advisor data will be considered valid by the manager. Problem impacts uLB versions 8.5.5.x and 9.0.0.x
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server Network * * Deployment Load Balancer for IPv4 and IPv6 * * users. * **************************************************************** * PROBLEM DESCRIPTION: The TLS advisor will not timeout when * * connection established but server * * does not respond. * **************************************************************** * RECOMMENDATION: * **************************************************************** Once a connection is established with the TLS advisor, a server Hello is sent and the advisor waits for a response. If no response is sent, the advisor will not time out and waits until the connection is broken.
Problem conclusion
Corrected the code to honor the receivetimeout and mark the server down when no response is received. Fix levels: 8.5.5.16 9.0.5.0
