This isn't really a race condition. The message occurs when the limit for
simultaneous HTTP sessions is exceeded. You haven't explained what the HTTP
server in Asterisk is being used for, so I'd start with investigating that.
Is ARI being used? WebRTC? If you do a packet capture on it do you see a
flood of incoming HTTP connection attempts?
