The error "HTTP JVM: Traveler: Lotus Traveler task did not respond within the allotted time frame (65,000 milliseconds) for action sync and operation key" is displayed on the server console.
This is caused by the traveler task binding to the wrong IP address in a server with multiple network interfaces.
It can be fixed by specifying explicitly which IP address that the task should use by modifying the following Sametime server configuration files.
Add the following lines to the Notes.ini (in Server Program folder) if not already present.
Where IP is the actual IP address which should be used.
Add the following line to the servlet.properties file (in Server Data folder).
After the changes above have been made a server restart should force it to use the new values.
