I am wondering what the reason causes my message-queue could easily get starved for new bits? How to avoid this problem with my message-queue? Is the problem of the wrong setting about the msg_limit for the message-queue? I do not understand how to set the limit for msgq. What it depends on?
I tried to make the bits loading thread "sleep" for only 0.005s, though still the underrun occurs. What is the reason of that? Thanks you so much for any of your suggestions.
