This happened again today.

I removed all the 2016_11_*.log files from there, which freed up about
16GiB.  Upon more investigation, it seems jetty is making these log
files directly, and "rotating" by just logging to a file with the
current day and removing files after a few days.

To change this to something smarter than can compress too, I think you
need to put log4j classes into the classpath and configure jetty to
use the slf4j facade to redirect logs and ... I dunno, it got too
hard.  fungi also went in a live-configured it to be less verbose.  I
think this also requires more configuration to be made persistent.

I've proposed [1] to just compress the logs and cleanup in cron which
seems like the KISS approach, at least for now.
