Oh! This happened to me always. I do not think there is a bug, but perhaphs either the scrip is getting killed somewhere due to some strange reason or it is supposed to delete 20 - 25 messages each time.
This has happened to me WITHOUT an exception and I cannot beleive that it could be due to any message header etc, problem.
As you may checkout my earlier message Trash bug or delete bug title from the posts I have made. This is explained more how I have solved it and think about it.
Interestingly the empty folder works SO EFFECTIVE in comparision to purge. May be because for purge function, it has to connect database so many times and put everything into RAM, as compared to only data of one user and the respective connection. However, I say this here without even looking at the code and hence it is a simple presumption, so I could be wrong.
