Maximum queue depth

To limit the backlog of messages queued for a client that is not consuming them quickly enough you can indicate a maximum queue depth for clients.

Choose this size carefully as a large queue size can lead to excessive memory usage and vulnerability to Denial of Service attacks, whilst a small queue size can lead to slow clients being disconnected too frequently.

The maximum queue depth for clients can be configured for a client connector in etc/Connectors.xml. A default value can also be configured in etc/Server.xml for connectors that do not explicitly specify a value.

These values can be changed dynamically at run time using System Management but they only take effect for new clients.
