Configuring Graceful Timeout
Many maintenance actions on Media Components (such as locking, restarting or upgrading) let you employ a "grace" period (graceful timeout) before the action is started by the Cluster Manager. The graceful timeout lets the Media Component continue processing currently active transcoding sessions until the timeout expires. During the timeout, the Cluster Manager doesn't allocate new transcoding sessions to the Media Component.
If all transcoding sessions end before the timeout expires, the Cluster Manager doesn't wait for the timeout to expire, but performs the maintenance action immediately. If active transcoding sessions still exist when the timeout expires, the Cluster Manager transfers all the transcoding sessions on the Media Component to other Media Components and then performs the maintenance action on the Media Component. Transcoding sessions that cannot be transferred due to unavailable DSP resources on the other Media Components are immediately terminated. These terminated sessions are indicated in syslog messages.
