Hi:

I am getting the following error:

10:39:52,416  ERROR [index.AbstractReindexComponent.threads] Reindexer   774 failed with error: 0913237278 Transaction must be active and synchronization is required: Thread[indexTrackerThread5,5,TraceableThreadGroup-7].

This makes Alfresco document upload and download very slow.

Could you please help me in rectifying this!!!!
