Currently we use a custom TCP protocol, and I find that when there are that many inbound connections, the OS starts to refuse them, and I need to back off and retry a few seconds later. Will I need to do anything similar with an ActiveMQ client, or will it handle that situation automatically? Can you recommend client or broker settings that will work better in that scenario?
