4 years ago @irispete this repo is for the ROS driver for these cameras. Are you using these with ROS?
Sounds like you are running 3 cameras on the same USB bus and might be running into bandwidth limits. I'd suggest you take a look at spinnaker's guide on multicameras at https://www.flir.com/support-center/iis/machine-vision/application-note/usb-3.1-multiple-camera-setup

System Description Camera Name and Model: FLIR Blackfly S BFS-U3-88S6M Operating System: Ubuntu 16.04 Spinnaker Version: 1.8.0.64, also tried 1.27.0.48 ROS Version: n/a
Computer details Processor: Nvidia Jetson TX2 RAM: 8 Gb
Multiple Cameras Only How is the triggering setup? Master/Slave or all slaves or all software triggered?
For USB 3.0 cameras: On same USB 3.0 bus or different buses? Is the USB 3.0 hub externally powered?
Do the cameras work with SpinView? Haven't tried this
Describe the bug When I run multiple cameras at a rate of 10 fps or greater I encounter the error: Failed waiting for EventData on NEW_BUFFER_DATA event [-1011] Sometimes this happens right way, some times it can run as long as 3 hours before I encounter this error. I have only tried with 2 and 3 cameras. The higher the frame rate or the higher the number of cameras, the quicker I will usually see the problem. I can duplicate the issue by running the AcquisitionMultipleCamera sample application, commenting out the code that saves the images to a file to speed it up, and increasing the number of loop iterations so it will run for a long duration. When I use Spinnaker 1.8 I see the buffer error, when I use version 1.27 it usually just hangs the application rather than returning an error. I have not tried lower frame rates to see if there is a cutoff, I need to get at least 10 fps, 15 if possible. The resolution of those cameras is 4096 x 2160
Here is the output of the device data from the sample app: Application build date: Apr 8 2020 15:42:54
Spinnaker library version: 1.27.0.48
Number of cameras detected: 3
