Nothing theoretically wrong with that code - my guess is you have a bunch of unsubscribed messages in a row. So here's a pretty lame patch that adds overhead by removing the potential recursive call. Let me know if this helps.

More findings: - it is an xdebug setting - it happens each time I rename a folder - it doesn't happen if raise that limit to 200

And one really weird side effect is, that the initial_page (or initial_view?) is reset to the default after this.

By the way, this also happens on each subsequent access to IMP, until I logout. With variations, like: ( ! ) Fatal error: Maximum function nesting level of '100' reached, aborting! in /srv/www/htdocs/horde/imp/lib/IMAP/Tree.php on line 1445 Call Stack # Time Memory Function

11/01/2008	Jan Schneider	Comment #3	Reply to this comment
It happened again this month. This might be some recursion protection from Xdebug though. I still wonder if recursively calling next() this often in the expected behavior. If yes, then this ticket can be closed.

I don't see this.
