Documents remain in "To be synchronized" state

Hi All,

I have created an index and attached a data source to it. This datasource consists of 5 text documents.

When I re-index the datasource, all 5 documents always remain in "To be synchronized" state. Repeated re-indexing is also of no use.

I have flushed the queue a number of times, restarted the portal and trex instance and performed re-indexing. Yet, all these documents do not move from "To be synchronized" state at all.

I am not able to figure out where the problem is.

Any suggestions on this?

Thanks in advance,

Pavithra
