Pool members monitored by the SASP monitor may be incorrectly marked DOWN when they should be marked UP.
Traffic handled by pool members monitored by the SASP monitor may be disrupted.
This may occur on affected BIG-IP versions when using the SASP monitor targeting a Load Balancing Advisor GWM (Global Workload Manager). This is more likely to occur if pool members monitored by the SASP monitor are also monitored by an additional monitor which has marked the members DOWN, or if one or more pool members monitored by the SASP monitor have been manually marked down (state user-down via tmsh, or Disabled in the GUI). This is not expected to occur with non-affected BIG-IP versions or when using the SASP monitor targeting a Lifeline GWM (Global Workload Manager).
Removing the SASP monitor from the pool or pool member configuration then re-adding the SASP monitor may reset the pool member status to the correct state.
None
