Interesting. What operating system are you using? I'm running systemd 229 on Debian testing and I don't have this issue, nor have I altered this setting. It would be useful to know what the difference is between our systemd installations. I don't see anything related to TasksMax in systemd-229's NEWS: https://github.com/systemd/systemd/blob/master/NEWS
