On initialization of NLMISC::createDebug , log*.log are deleted and recreated. Before unlinking 'log*.log' a chmod is made, if the chmod fail we are displaying a warning message via nlwarning.
Because NLMISC::createDebug is not initialized, we are looping for ever and exhaust the stack.

Maybe moving "INelContext::getInstance().setAlreadyCreateSharedAmongThreads(true);" on the top of the function, will keep console logging online.
