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:
