I have a situation where the programme counter(PC) shows that vxworks msgQreceive function has been called by task A and Q is full, still I am not picking up the messages. There is no other task registered to receive messages from this Q. The sending task B, which is ISR in this case, is getting timedout everytime it tries posting new message in it. A's state is PEND which means I am waiting for some resource to get free but PC shows I have called vxworks msgQReceive and currently at qJobget+0x018 location. There seems to be two causes now(identified by me): either vxworks qjobget task is not able to do semTake or no messages in Q. But Q is full and semTake failure seems unlikely(though I dont have a mechanism to check so). Besides explaining root cause for above, can anyone suggest how to get my task in READY state again? I also tried flushing the Q; on doing this, more messages get posted in Q but A still doesnt pick up any :(
