when i use evictor, sometimes i can catch this:
error: Saving thread killed by exception: MapI.cpp:998: Freeze::DatabaseException:
Db::put: DB_PAGE_NOTFOUND: Requested page not found

and my application is core, why?

    This error indicates a problem in the Freeze evictor saving thread, while writing to the database. This kind of error should never happen, and that's why Freeze aborts your process.

    Could you post a test-case that reproduces this crash?
    Also, please include your Ice version, Berkeley DB version, platform etc.

    Thanks,
    Bernard

    in evictorI.cpp，
    function registerFatalErrorCallback is seem to be a bug

    Freeze::FatalErrorCallback
    Freeze::registerFatalErrorCallback(Freeze::FatalErrorCallback cb)
    {
    IceUtil::StaticMutex::Lock lock(fatalErrorCallbackMutex);
    FatalErrorCallback result = fatalErrorCallback;
    return result;
    }


    static Freeze::FatalErrorCallback fatalErrorCallback = 0;


    fatalErrorCallback never be change by cb。。。

    maybe should like this：

    Freeze::FatalErrorCallback
    Freeze::registerFatalErrorCallback(Freeze::FatalErrorCallback cb)
    {
    IceUtil::StaticMutex::Lock lock(fatalErrorCallbackMutex);
    FatalErrorCallback result = fatalErrorCallback;
    fatalErrorCallback = cb;
    return result;
    }

    Please upgrade to the latest version of Ice. It should be easy, since you're just experimenting with Ice.

    Cheers,
