i wrote a program transfer bits from a8 to m3-video, and then back to a8, when i call System_linkDelete to delete link_bit_in_hlos, it hang, does anyone know the reason ?

    There was a divide by zero bug in ipcBitsInLink which would cause a exception when ipcBitsInLink is deleted before receiving even a single frame.This has been fixed in DVR RDK 3.0.From the logs it looks like you are hitting this issue. If possible pls migrate to latest RDK release RDK 3.0.1 and  let us know if you still see the issue .
