Daily cronspam like:
/etc/cron.daily/logrotate: uwsgi-graphite-web stop/waiting uwsgi-graphite-web start/running, process 15986 gzip: stdin: file size changed while zipping gzip: stdin: file size changed while zipping gzip: stdin: file size changed while zipping gzip: stdin: file size changed while zipping
Last attempt to fix the cronspam: https://gerrit.wikimedia.org/r/308526
The main issue seems to be that graphite-web does its own internal log rotation, that as far as I can see is not configurable until version 0.10 (meanwhile we run 0.9.13+debian-1):

Pythons own log rotation can be disabled using the LOG_ROTATION setting. This is useful in case of running multiple WSGI workers. See also: Github Issue #499.
Maybe disabling compression could help?
