If it's intermittent and it happens on the same query, then it has to be either connection problems or a timeout on a long query. Have you tried putting the .Fill() in a try/catch? Does it generate an exception at all? It should at least do that. If there is no exception being thrown, then perhaps you have a very long timeout setting and it appears to hang or freeze so you end up killing it before the timeout period is over.
