UNIFYBroker Entity Search Throwing an error

Hi Guys,

When clicking on the entity count to do an entity search (Both Connector and Adapter). I can't seem to perform an entity search. I get the following error: 

Error

 DataTables Error

This error hasn't always occurred, however recently the error is appearing for connectors/adapters with high entity counts (lower entity count connectors/adapters seem to be fine).

Current IDB version: v5.3.1

Troubleshooting so far:

* Restart the UNIFYBroker Service

* Rebuilt all indexes on the UNIFYBroker Database

Let me know if you need more information.

Thank
