-- is this a problem of the manager or this is an internal error of wincc oa ?? Mostly i wonder about these lines : "Default branch called, Variable, allocate, Couldn't allocate Variable, unknown Type: 367"

As the Event manager tells you it could not handle the message you sent to it, it seems the message stream was corrupted in your managers memory.
One guess could be you're using operating system threads in your manager C++ code and send messages from different threads (which is not supported by our api),
or you mess up your memory on a complete other situation.
You really need to check your code.
