I am seeing an issue with Teaming 2 that is becoming more common and is quite annoying. A user accesses Teaming normally, but the Tasks Due and Tracked items are empty. When the user enters a Team workspace, the General Error appears with the following message:

Please contact your System Administrator for assistance.

class org.kablink.teaming.search.LuceneException
Error searching index [/icecoredata/lucene/liferay.com]

The admin user must then login, go to Site Administration, and re-index the site. The re-indexing always completes and reports no errors found. Then everything works fine. This is now occurring at least twice a day.

Does anyone know why this happens or how I can prevent it?
