You get these messages when your blocks cannot keep up with the rate of data coming from the source. Some blocks (FFTs come to mind) operate more efficiently when given data in chunks of powers of two, but I would guess changing your vector length wouldn't help too much.

You can write the data out to a file and read it back in. This way you will not lose any data (but you will run slower than real time).

This is not correct.
What you need to understand from the warning is that:

   a - your system will use more memory than if you didn't have the warning
   b - your system might run slower than if you didn't have the warning

Your system WILL STILL RUN CORRECTLY. This is only a performance warning, NOT an error.

Please see my other message for clarification.
