Connect 2018.2 Server Enhancements
Engine Setup
The settings for the number of Connect Server engines to launch has been removed from the
"Scheduling" settings page, which controls how the engines are actually used. They have been
moved into a new "Engine Setup" page that controls how many engines of each type are to be
launched. This also simplifies the Scheduling preferences page.
Automatic Engine Restarts
To safeguard server availability restarting the Connect engines periodically is recommended.
Previously Connect engines would restart every 8 hours by default, and all would restart
simultaneously. Connect 2018.1 added the ability to have engines restart in case of very bad
memory usage as well. Connect 2018.2 has now introduced several improvements to allow
further control over engine restarts:
l Rolling restart
Causes engines to restart one by one, instead of all at once. On systems with many
engines this reduces the impact of restarts and increases engine availability.
l Schedule restarts in quiet hours
Instead of restarting engines after a certain amount of time, they can now be restarted
during a specified time period. This allows engine restarts to be scheduled outside of
business hours.
Improvements for high workload situations
On busy systems, with many requests to the PlanetPress Connect Server (such as hundreds of
simultaneous PDF preview requests), the internal communication between the Connect Server
and the engines can now be set to use a different port from the primary connection port. This
