Oh, I forgot. You do have plenty of swap space compared to RAM, yes? If
you're running w/o swap, or little swap, the default settings of
overcommit_memory = 2 will cut your available RAM by a factor of 2.
This thread is interesting reading:

Since disk space is usually cheap these days, my rule of thumb is (the
old one):
swap = 2 * ram
read it this way: "it you have 32GB of RAM, you can afford 64GB of disk
storage"
BTW, this is a good idea both with overcommit on and off, IMHO.
