It means exactly what it says - too many clients.

Well - you probably had 100 connections then (actually, 100 - your
superuser reserved connections, default=2).

There are two possibilities:
1. You had 100 users last Monday
2. You are using more than one connection per user.

The second is the most likely. Turn connection logging on and try with a
couple of users to see how many connections you generate as you use the
site.
