Hi Woo, first of all I checked and don't have the messages myself. So I was looking around and found [1] (and much more like it).
It seems the TL;DR is that these are systemd debug messages, enabled by setting the environment variable SYSTEMD_LOG_LEVEL=debug, or the debug and systemd.log_level=debug options on the kernel command line. Please lower the logging level to disable them. If you find it woudl be interesting if that debug was set up by a package accidentally (maybe a bug) or by you intentionally (which is fine) [1]: https://lists.freedesktop.org/archives/systemd- devel/2017-February/038371.html ** Changed in: php7.0 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711795 Title: syslog flooded with PropertiesChanged To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.0/+bug/1711795/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
