Wow.

I assume you were killing them as root, right?

Unkillable (with -9) processes mean they're in uninterruptible sleep.
Usually this means waiting for some remote filesystem.  Do you use NFS
on this server?  Or a fuse-based filesystem like sshfs?

Can you see anything suspect in dmesg?  Can you strace the hung dpkg
processes and see where they're blocked?
