Appian engines will replay transactions in an event of an unexpected shutdown. When this occurs, the engine startup time will depend on the number of transactions it has to replay. A large number of transactions can delay the engine start-up time.
This article outlines the following:
On the server which hosts the Appian Engines, navigate to <APPIAN_HOME>\logs\service_manager.log and search for log entries of the following type which have details on the engine name, number of transactions to replay and the approximate time this will take:
