SUMMARY
I started receiving the error "Maximum number of clients reached" when trying
to open new X-based programs.
Upon investigation, I saw that `kded5` was using 146 connections -- the next
highest program was using 8 [1]. Restarting kded5 solved the problem.
[1] I used the script found here to identify this:

STEPS TO REPRODUCE

of clients reached" when trying to start a new window.
