I have a serious problem with my Piwik. Sometimes, the visitor counter is raised with every page view. This happens only on some visitors, let’s say about 1%.
Here you can see a peak at 17h, which was caused by only one vistor:

Here the visitor log:

I checked the database table with a SQL-Query. The “cnt”-column shows the number of visits of an unique user in one hour. It should’t be higher than 2, because my visit_standard_length is 1800.

The SQL query shows, that this problem happens only on some specific visitors (same “visitor_idcookie” in different row). Most of them are Firefox users. Perhaps a cookie problem?
With this issue I can not trust the Piwik results any more. :S
