[syslog-ng] How to detect loss of connection of remote syslog-ng client.

Hi I am using syslog-ng server on Solaris box and the syslog-ng clients are running on Linux box. When client ( linux ) box crashes the streaming stops. But the syslog-ng server assumes that the client is connected and keeps the connection. Is there any way to detect this condition and close the socket connection to the client which no longer exists.
