Ever since Qui-Gon's death, Obi-Wan has believed that it would have been better for everyone if he had died instead of his master.
Over the years he has become more and more reckless. At first it could be chalked up to the influence of Anakin but once his padawan became a Jedi Knight and Obi-Wan had to work more often alone, he became even more reckless - to the point that people start to openly call him suicidal.
Mace Windu was a good friend of Qui-Gon and had been keeping an eye on Obi-Wan ever since his death. He's the first to notice that something is wrong.
When one of Obi-Wan's mission/battle goes exceptionally wrong and he ends up in the med-bay half dead, Mace Windu put him on suicide watch.
