If you receive an error that says a block or frame is being dropped because a packet
is unavailable for resend, one likely cause is that the buffer size of the socket could
not be set to the reported value, for example 1000000.
See your system administrator about using sysctl for net.core.rmem_max. For
example, the system administrator could try:
sysctl -w net.inet.udp.recvspace=1000000

If your camera does not start a new acquisition at block 1, the toolbox will attach the
block ID (frame ID) as metadata to the frame. If you want to know if you lost initial
frames, you can check the metadata – if the first frame's block ID is not 1, you may
have some missing frames. For example, use this command in MATLAB:
[d t m]=getdata(vid,2);
m(1)
The answer will include the Block ID and the FrameNumber.

Run the imaqsupport function for further troubleshooting information.
