I concur. I have lost track of R's internals long ago, but in a previous life
analyzing the Apache HTTP server's actual memory use (something that focused
on shared RAM, quite different from what you'd probably like to do), I found
that if you really need to understand what's going on, you would need to look
On Linux, you'll find the details in the /proc/[pid]/maps and /proc/[pid]/smaps
pseudo-filesystem files, where [pid] is the process ID, im your example 6210.
That's where you really see what's eating your RAM. :-)
