Hi Travis, How many clients did you have connected to this server? Usually the default is 8K file descriptors. Did you have clients more than that?
Also, if clients fail to attach to a server, they will run off to another server. We do not do any blacklisting because we expect the server to heal and if it does not, it mostly shuts itself down in most of the cases.
