Hi ALL,
I'm working on RHEL4.
I want to find out list of all third party software installed on RHEL4
machine. Some of these softwares are directly compiled from source and some
are installed through RPM's,, and for some we are directly using the
binaries. Looking for a single command that can find out 3rd party installed
softwares.
Please Help.
Regards
Sudhanshu Chopra

If you'd like a more detailed explanation than Joseph's reply, check
out http://gentoo-wiki.com/FAQ_Linux_Memory_Management or use your
favorite web browser and search for "linux memory management".

Not sure if that helps you, but "Mapped" refers to devices, files, and
libraries which have been mmaped (memory mapped) into pagetables.
(Cf. http://en.wikipedia.org/wiki/Mmap)
Without knowing your application, it'd be hard to judge whether
3529560 kB out of 8164748 kB is reasonable or not.

You don't have any problems with the north bridge overheating?
