MORE INFORMATION

When the maximum inbound connection limit has been reached, the IMS should immediately reject any new inbound connections. Instead, the IMS queues the connection for reverse DNS resolution. This can result in a large queue of connections to be resolved.

The maximum inbound connection limit is 30 by default. To set the maximum inbound connection limit in the IMS:

Click Connections. On the Advanced tab, type the maximum inbound connection limit.
