# Destination Backlog Swapout

Specifies the number of messages that may be stored in the server's memory before message swapping is enabled. The limit given is for each destination. For example, if the limit is 10,000 and you have three queues, the server can store up to 30,000 unswapped messages in memory.

The specified number may be any positive value. When Destination Backlog Swapout is 0, the server attempts to immediately swap out the message.

By default, the limit for each destination is 1024 messages.

## Classic Configuration

The limit is set using the destination_backlog_swapout property in the tibemsd.conf file:

    destination_backlog_swapout = number

## Administration

This property cannot be set using the administration tool.
