Unfortunately, I don't have much insight into JVM issues. But I found a SO
question (
http://stackoverflow.com/questions/6754628/eclipse-crashes-with-unable-to-create-new-native-thread-any-ideas-my-setti)
indicating
that the thread stack size could be a problem. What happens if you try this?
conn <- blpConnect(jvm.params="-Xss1024k")
