Hi Cliff,

You can increase the heap size by changing the maximum heap size of the java
virtual machine. To change it to 512 MB:

 conn <- blpConnect(jvm.params=c("-Xmx512m"))

But on a 32 bit machine you cannot go much beyond 1024m. If your data is
more than that you would have to do it in multiple calls. If you close the
connection it would clear the heap and you can make a new connection for the
next set of tickers.

Regards
