Portal Acitivity Report Data Collector

Hello,

We had portal activity reports functioning in our production portal environment. Recently the portal activity reports stop reporting on data on January 20th. We're on EP 7 SP13. I'm not sure of why it's not reporting, but I am certain that these pages have been access after the 20th. I check the com.sap.portal.activityreport.core service and the settings hasn't change and the service is turned on. Week have weekly restarts so restarting the service will not benefit. Has anyone ran into this problem?

Regards,

Francis
