Hi

This error explained generates:

VISA: (Hex 0xBFFF00A6) The connection for the given session has been lost.

You can right click on the error cluster and see that explanation, by selecting explain error.

One of the things I recall from a long time ago might be a loose connector in the gpib setup especially if more instruments or more cables are connected. Even a cable can be damaged, but that would probably result in a more permanent error.

You can also check your program if you are opening and closing visa sessions all the time this can happen. As a rule I only open a session in the beginning of my program and close it just before stopping the program. There is a finite number of opening and closing visa sessions, finite but high number.

Or some memory management error that only happens after a long time running.

Maybe you have more information and we will be glad to help you.
