>OK. That wasn't clear. To be sure: you're saying a DLL was replaced immediately prior to each occurrence of 'Application End' ?

Yes, for that part, everything is ok.

>Application_Init() does not exist and Init() is not an event - its an overridable method. Are you saying that with the above code in the global it never gets called?

Ok, that explains why it was not going into that one. I saw that one on the net so probably they made a mistake on the code over there.

>Also, as per yesterday, I'm not sure that you have really narrowed this down to something that only happens when the application re-cycles. Unless you try with the long-running page and over-lapping hits and never get the problem it's not proven.

I will try to find more information on this.
