    This high load may be due to the "nightly" rsync you see below:

Looks more like a runaway python to me.

    PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
   1927 www-data  39  19 1090m 740m 3596 S    0 12.1 425:43.54 python
   2691 nobody    20   0  109m  58m  33m S    0  1.0   0:02.24 git
  10840 root      20   0  107m  48m 1556 D    1  0.8   1:19.83 rsync

(BTW, not to be teaching my betters, but I suggest "top c" to show
command lines and not just names.)

But anyway ... Michael, what is the rsync job doing?  It is easy to make
it consume less resources in exchange for more time, --bwlimit=100
(Kbytes/sec) or whatever number turns out to be good.  It should
probably also be running with nice -19.

Best,
Karl
