Problem: The serverUp script might run when you issue commands for Load Balancer that affect the status of servers

A quiesced server has a weight of 0, which is the same value as a server that is detected down by the advisor. If you run a unquiesce command on a quiesced server, the executor function saves a value of 0 for the weight that determines if the state of the server has changed. When the server is unquiesced, the serverUp script might run because of this saved value.

Weights are set by the manager during a manager cycle. At the start of the manager cycle, the manager retrieves the current weights from the executor function. The manager uses these values as the last known weight to determine if the status of a server has changed:

The chances of experiencing this problem increase with larger configurations because the manager cycle takes longer to run. Also, there is a higher probability that the manager cycle will be in progress when the unquiesce command is issued.
