I have a remote server running syslog-ng collecting messages from network devices that are local to it and transferring them to a central server using TCP. This is to avoid messages being lost when UDP is used a a network problem occurs. All works as it should and I have tested breaking the link between the local collection station and the central server; the messages are passed to the central server when the link is restored. I had a question regarding how long the remote server will hold on to the messages when it cannot pass them to the central server. Is this a time dependent parameter, memory limit or hard coded somewhere? I couldn't find a destination driver configuration parameter for this in the documentation. Jim Mozley
