Discussion count doesn't update itself

Vanilla 2.5, fresh install. I've had this happen on multiple servers.
Discussion count doesn't update unless I run dba/counts. dba/counts shows this after running it:
What is the '100%'? Is that supposed to be there?

I have the same problem.
I don't know what's wrong with counter but the 100% strike it's normal
Have the same problem. The counter doesn't update itself.
It works if you use: www.yourforum.de/dba/counts but you have to repeat it several times.
The included function "DB Update Counts" in the dashboard doesn't work: www.yourforum.de/dashboard/dba/counts
Hope anyone can help.
