mass-check made my server unresponsive for five hours?
I woke up to find I couldn't get into my server, and linode's graphs showing
that it had been swapping severely for five hours. With enough patience, I
eventually got in, and found:

The bind memory usage is about normal, due to mirroring dnswl.org with it.
I just removed my mass-check cron job. Anybody else seeing substantially
increased memory usage from mass-check lately?
I had another bout of swap thrashing not long ago, now suspecting it was
the same thing.
This VM has 747 megabytes of ram.

My task went as usual today. No problems whatsoever. I have 8 gigabytes
RAM in machine doing it, and 1 gigabyte in DNS server.

Everything that you know is wrong, but you can be straightened out.

With that amount of ram I wouldn't run more than 4 simultaenous jobs.
Try lowering the job count
