Does Race conditions occur in Queued state machine

hI 

I'am developing a vi in which i use a producer consumer design pattern.
the producer enqueue's the states for the consumer. but at some point of excecution i wish to enqueue the next state of the consumer statemachine, from within the consumer state itself. does this cause any problem??.
 in other words can i enqueue data within the consumer loop also. so thet the next state of consumer will depend on the data enqueued

Thanks
