As mhite suggested, it looks like you've disabled the node address or pool IP:port. This will allow existing connections to continue as well as clients with a persistence record to continue using the node or pool member.
If you want to prevent all new connections to the node or pool member, you can set the state to offline. Existing connections will be preserved, but new connections will not be allowed.
See this post from Joe for details:

Determining The Toggle State
When querying the Toggle state (enabled, disabled, or offline), one must look at the monitor and session enabled states. The three possible combinations of these two values will yield the appropriate toggle states.
Monitor State Session Enabled State Toggle State
STATE_ENABLED STATE_ENABLED Enabled (All traffic allowed)
STATE_ENABLED STATE_DISABLED Disabled (Only persistent or active connections allowed)
STATE_DISABLED STATE_DISABLED Forced Offline (Only active connections allowed)
