Unable to query recordset on Log Group Reason: ConnectionWrite (send()).General network error

I'm using kepware datalogger. I have configured different DSN for different table login purposes. All the loggers were working fine in the application server. And suddenly this happening randomly for dataloggers

Unable to query recordset on Log Group Reason: ConnectionWrite (send()).General network Error.

Does anyone have any idea what this error means and how to resolve it ? Already the application is in live mode. But this is happening randomly. Network side everything was good having good ping.
