I was doing some research and saw the same similair information. Some sites were saying you can increase the processing identifier limits but I dont think I will try those. Yes the same error occurs when running the cdma_txrx. I will try reducing the number of filters to a smaller value, and yes I understand there will be tradeoffs in doing this. I am using a laptop by the way so it probably cannot handle as many threads because of its memory, RAM, processor size etc.

Some googling showed that this happens when you are trying to spawn more threads than your machine can handle.

From your previous post/discussions I understand this happens when you run the cdma_rx file.
The part of this program that generates a lot of threads is the aqcuisition filterbank
which we have made highly parallelized.
If this is the case then it should also happen running cdma_txrx (please try it).

Recall that gr-cdma is fully parameterized by the user.
So to fix this (this is not a bug, it is the feature of the system) try to change the variable
n_filt=51 to some smaller value (try 11).
I hope you understand what the tradeoffs are (reduced capability of receiver to handle frequency errors).
