Is there a way to find out if Linux kernel is leaking memory by running some commands? I am almost positive that the linux kernel is leaking memory. However, the top and free -k do not reveal much. Is there a way that I can look at how much memory kernel has allocated and hopefully some kind of a memory map too? Thanks for any inputs

    Your question is pretty specific - you might get a more useful response if you describe the behaviour that you're seeing and say why you think there might be a kernel memory leak. – Tom Shaw May 26 '11 at 12:16

Try looking at /proc/meminfo:

$ cat /proc/meminfo

The resulting fields are described in the kernel documentation.

If you see Slab or KernelStack growing over time then maybe you're on to something. However, if the big consumers are AnonPages, Mapped and Shmem then it's a userspace issue not a kernel issue.
