Too funny.  So in other words there isn't a problem at all.  What you
thought was RAM usage was really just a memory-mapped file.  That's why
Antoine said that using VSS to determine memory usage is not valid at
all in determining memory footprint.  VSS shows all kinds of things from
shared libraries to locale archives that have zero impact on RAM usage.
 Every app will show at least the size of glibc in its VSS number.

What is "too much memory" anyway?  What do you mean by "consume too much
memory?"  Now if your script has a resource leak and is long-running,
then that's a problem, but the solution is to fix your resource leak,
not have the OS kill your app when it exceeds the RLIMIT.
