java.lang.OutOfMemoryError: unable to create new native thread

Thanks to all who responded to my problem.

An interim update. I am still not sure what has been happening but Rbbg is now working. 

I use RStudio and recently upgraded to the latest version. It appears that the upgrade did not work as smoothly as it should have done since when I uninstalled and went back to the earlier version of RStudio it started to work again.

I have opened up a discussion thread on RStudio to see if any reader can shed any light on the problem.

When I hear something, I will post again here.

Thanks again

Gordon

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")

Sorry, perhaps some more information.

If I run the code from RStudio, I get the errors already mentioned. But if I run it just from the RGui, the connection is made and data can be downloaded.

I am having this problem occasionally as well.?
Solution is either a gc() or restart of r terminal . I also notice that it occurs when I am trying to open up fourth or fifth instance of the connection without closing earlier ones.

Can you please clarify if this happens with a cold booted machine with
nothing else but R and Bloomberg running -- or if you've already run
other commands.

Hi

I am having a problem connecting to Bloomberg.

Here are the symptoms ....

library(Rbbg)

I can connect to Bloomberg via the API

Does anyone have any ideas?
