Memory leak?

[Damian Lubosch]

Hello!

I just checked the memory status of my new Dragonfly-based server.

the top command prints out:

The machine has been idle for most of the time since the last reboot. How can I check which applications consumes >6GB of memory? Can I check somehow the consumption of the kernel / its drivers? Sascha Wildner and I patched the kernel to support the newest twe driver from FreeBSD.
