Opened: Oct 24, 2023

Severity: 3-Major

Symptoms

While requests are delayed in TMM due to various reasons, their virtual server and BADOS profile might be deleted. This may lead to a TMM crash.

Impact

Traffic disrupted while tmm restarts.

Conditions

-- BIG-IP System, passing traffic. -- The virtual server has objects attached, such as complex iRules or BADOS, which cause the requests to take more time to get through the tmm. -- A connection is dropped while the request is still being handled.

Workaround

If possible, avoid using objects that cause requests to be delayed, such as iRules and behavioral DoS.

Fix Information

None

Behavior Change
