In certain circumstances the BIG-IP system may load balance connections to a node or poolmember over the configured connection limit.
BIG-IP system may load balance connections to a node or pool member over the configured connection limit.
- Node or pool member configured with connection limit. - L4 or L7 virtual server. - Persistence configured on the Virtual Server. - Very high load on unit.
Remove persistence or use another method of limiting the connections (rate limiting or connection limit on the Virtual Server).
The BIG-IP system now correctly enforces the pool member/node connection limit.
