Andre,

Does the batch script always fail, or is it sometimes successful? You've
probably tried running in batch and interactively one after the other, but
if not please do that to make sure it isn't a timing issue with the
Bloomberg connection.

Also, you can turn up the logging in Rbbg: conn <-
blpConnect(throw.ticker.errors = FALSE, log.level = "finest")
Maybe that will shed some light on the problem.
