xfer-timeout
This allows you to control how long the server should wait idle for a block
of data from the remote client before it consider the connection irrecoverably
lost. This timeout exists to prevent the server from waiting indefinitely
if the remote client locks up or loses the connection.
The value is specified in seconds, and must be greater than zero.
This timeout value should be relatively large to account for the TCP window
of transmission.
Other timeout values you can configure are the connection establishment
timeout (conn-timeout) and the control
connection idle timeout (idle-timeout).
Examples:
xfer-timeout=3600
xfer-timeout=60
