Only network stuff here. Since there is no problem when disk is not
used, I think we can rule out network stuff.

So you are using tmpfs, *not* ramdisk. Tmpfs lives in memory and
occupies amout of memory equal to amount of data stored. Unlike ramdisk,
memory is reclaimed when you remove files from tmpfs and when you umount
it.

Ok, got the picture.

You should have included your config too, since you are using a custom
one. We need to know what drivers you have compiled in your kernel. It's
called .config and located in the build directory of the kernel.

And of course, you did not include the most important stuff --
/proc/meminfo, /proc/slabinfo, /proc/diskstats and /proc/vmstats from
time when it exhibits the problem. Also you forgot about /proc/swaps (it
may be empty or not even exist, but you should at least say so).
