We have a simple application with multiple NSView subclasses (like Buttons, TextFields, etc.) that are being updated every couple seconds with status information. After a couple days of running continuously the application will lock on this stack trace:

This is running on a 10.6.1 OS X machine. I searched the archives and googled but there's very little about this.
Any pointers, hints, or workarounds?
