Hope this time round I am following the std practice. :-)

I have a total of 16 MB RAM. My main concern is that I was running the same
set of applications earlier on linux-2.4.19-rmk7-pxa1 and didn't get any out
of memory. I am running the same application and get the OOM, though the
appearance is not uniform, at times it comes on a freshly booted system and
at times it didn't come when the system is on overnight.... Why I am getting
here??? Is there any problem with linux-2.6.13?

I have tried to check the application for memory leak with no success. There
seems to be no memory leak.
