    Message: Attempted to read or write protected memory. This is often an indication that other memory has been corrupted.

    Are you using Telerik controls?

     Thanks for your answer.

    I don't use Telerik. I have rather low level web service which doesn't use pages architecture at all. It is a set of sync and async http handlers.

    Also there are paraller threads running in the context of the application. Threads are created by Thread class or are taken from ThreadPool.

     I don't see that the second link is connected to the topic. Can it solve the problem?

    More info: sytem is running Windows Web Server 2008 64-bit.

    It can help with the error on the corrupted memory.   I ran into this with MOSS and W2k8 / x64, it helped with the error.
