@GregFreeman thank you for your time.
We also wanted to know if anyone has experience with this configuration, FPGA and Databases. Now, we are not sure if we can use this combination.
On one side a low speed for recording in the database and on the other hand the speed of acquisition of the FPGA. We have tried different sample rates, different sizes for the FIFO in the FPGA and the HOST, different read speeds but in the end, always that problem comes up.

I have not done that specifically. But, the troubleshooting is the same nonetheless. Unless you can narrow down what the problem is, it is useless to blindly try different things. That error comes up in the development environment, when you lose communication with the controller, most often because the controller is too busy and your debugging takes lower priority when it comes to RT systems.
My suggestion is to look at the distributed system manager. Determine if your memory and CPU usage are high. Then start disabling parts of the code to determine where the bottleneck is. Once you have determined that, you can play with your code to optimize it. For instance, you're assuming the data to the database is the problem. What if that issue is being caused because you have a tight loop with no wait function in it? And, because that tight loop is taking up all of your CPU, your loop to write to the database won't get a chance to execute. In this case, troubleshooting the streaming to the DB itself is quite useless.
My next suggestion, post the code in question to get feedback.
