Hi all, Maybe this is a known bug, but I couldn't find any mention of it...if you ommit a delimiter in the CSV data set config element, it seems that JMeter starts using enormous amounts of memory (2G for 5 threads, 1 aggregate listener, and one HTTP sampler). I don't know why this is the case, but several test runs without a delimiter ran out of memory and several test runs with a comma delimiter ran OK. Hope this help someone else avoid confusion.
