Re: Random locks ups in qemu

I see that all of the memory is in use for the disk cache, I will try the drop cache stuff.

I still think it sounds like a possible memory leak. When it starts slowing
down try running `free -h` and check how much available RAM you have. You
can then run `sudo sync && sudo sh -c "/usr/bin/echo 1 >
/proc/sys/vm/drop_caches"` running `free -h` after this should show that you
have a lot more RAM.
