Hello, I am in fly-by mode as I am still more than busy, so I just dumb this one out for anyone interested. Adapt it for your needs if you like it.

FW: R memory management
Hi, I'm using R to collect data for a number of exchanges through a socket connection and constantly running into memory problems even though task I believe is not that memory consuming.
