Trying to open page http://fi.wikipedia.org/wiki/Template:P%C3%A4iv%C3%A4malline
causes i timeout. Viewing the source works:
http://fi.wikipedia.org/w/index.php?title=Template:P%C3%A4iv%C3%A4malline&action=edit
. I Suspect that it has something to do with recursion as there is
{{{{PAGENAME}}}} in the source.

That cause an infinite loop: the template is calling itself.
So basicly don't use it :o)
What are you trying todo exactly ?
It's used to include short summary according of given date to date page. Look
for example http://fi.wikipedia.org/wiki/1._tammikuuta . I thought infine loops
were hammered out? Also i think brion investigated the page already and got some
weird results.

Oh, I get it. For those still staring in confusion, as I was, the trick is that
*once used on a page*, {{PAGENAME}} refers to the page *containing* the
template, not the template itself. So because {{foo}} causes the inclusion of
[[Template:Foo]], not [[Foo]], {{{{PAGENAME}}}} *on anything other than a
Template page* includes the *template* with the same name as the current
article. i.e. within the article [[Bar]] {{{{PAGENAME}}}} is actually equivalent
to {{Template:Bar}}. So that template does make sense, it just eats itself when
you view it directly.
As for the bug, I wonder if the problem is that the code never checks for a page
*directly* including itself, because it seems such an odd thing to happen?
Unless, of course, the bug is caused by something else on the page...
Oh, and I think there's a possible workaround - if the template wasn't stored in
the template namespace (move it to Wikipedia:Päivämalline or something) it
wouldn't be trying to include itself any more (it would be trying to include
Template:Päivämalline, which then wouldn't exist).

Loop detection seems to have been improved by Brion since 1.4beta6 about a week ago.

Marking as fixed, because none of the revisions of the supplied URL cause a
timeout any more (fi now running REL1_4rc1+).
