Opened: Oct 05, 2020

Severity: 3-Major

Symptoms

Virtual server resets all the connections for rstcause 'VIP disabled (administrative)', after all the conditions are met. Once it happens, the virtual server starts resetting all the incoming connections for rstcause 'VIP disabled (administrative)'. This continues even after the connection limit is deactivated.

Impact

A virtual server continues resetting new connections.

Conditions

-- There is at least one pool member that is DISABLED. -- Other pool members have a connection limit configured. -- A configuration change occurs while the connection limit is activated, and the change lowers the connection limit value, for example, the value is changed from 10 to 5.

Workaround

Use Forced offline instead of disabled to prevent this issue.

Fix Information

The BIG-IP system no longer continually resets new connections when the connection limit is lowered while it is being enforced.
