apt-get MergeList problem

If you have the following error while calling apt-get update:
# apt-get update
{...}
E: Dynamic MMap ran out of room
E: Error occurred while processing util-linux (NewVersion1)
E: Problem with MergeList /var/lib/apt/lists/ftp.debian.org_debian_dists_etch_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
The first solution is to try removing all downloaded lists:
# rm -vf /var/lib/apt/lists/*
Or move to some backup directory and remove from there later if there're no other problems.

If it doesn't help, try to find same of very similar repositories in the /etc/apt/sources.list and remove one of them. They can conflict with each other. Don't forget to repeat the first solution in order to clear cache
