Scheduled update jobs get stuck in showing status "IN_PROGRESS". 

In the Spotfire Administration UI > Scheduling & Routing > Activity, the Scheduled Update rule show status "IN_PROGRESS" and never gets to status "COMPLETED".

In the Web Player log, one might see that log entries for 
"Send life cycle event 'MemoryStatusChangedMonitoringEvent: Status Ok..."
and
"Send life cycle event synchronously 'Spotfire.Dxp.Framework.Monitoring.OpenedAnalysisLifeCycleEvent'..." 

However, in the server log only the 'MemoryStatusChangedMonitoringEvent' is seen.

In the Web Player log file, it may not be a single piece of information about communication issues at this time - it seems like 'OpenedAnalysisLifeCycleEvent' is just getting lost. That is - Spotfire Server does not get the message that the load is completed, which causes the Scheduled Updates job to stay in an infinite wait with status "IN_PROGRESS".
 

A Scheduled Updates job gets stuck and is not executed next time as per schedule even when services are free. This is a known issue in version 10.0 and lower, which has been addressed in version 10.1.0.

This is a known defect which has been addressed in TIBCO Spotfire Server version 10.1.0 and later.
