Symptom

An "Error Writing to the Socket" error can occur during JET Acquisition.  It can cause complete data loss until the acquisition session is stopped and restarted, though Ponemah will still be running and “collecting” flat lines after the error occurs.  

Resolution

DSI has only encounter the “Error Writing to the Socket” error message during JET data collection when there was a communication interruption between the receiver, switch, and computer. 

The primary way of this happening would be power loss to the receiver—even temporarily.  Power loss to the switch could also cause this since all communication is routed through there to get to the computer. 

Checking to see if there was a power outage in the facility is the first thing to verify (even if the power is connected to a UPS) since this has been a cause historically.  We have also seen this occur due to a faulty Ethernet cable with a bent pin causing communication turbulence, and once due to a faulty DLink POE adapter that cause intermittent power issues to the receiver.  Try swapping cables or power supplies if an obvious cause is not apparent.
