Node crashes after about 30 seconds

[k-kleber]

Hello, My camera node keeps crashing after about 30 seconds. Here is the output:

After this I can close it using ctrl-c and restart it. Then the same happens again after about 30 seconds.

I am using Ubuntu 16.04 and have the same issue when using the apt repository and the github's master branch.

Please tell me what additional information you might need. Thank you for the help.

Edit: After using a higher quality usb cable the problem takes longer to occur, but still does. Additionally, the above mentioned errors don't always stop the camera from working and could be unrelated. When the camera crashes and the node is closed, using ctrl-c, the following output is produced:

Judging from this, I believe that there might be a problem with the camera_nodelet_manager, as it is escalating to SIGTERM when closed, but closes normally, if the node is closed if the camera node did not stop working.

I am getting the same issue... were you able to find a solution?

It is a camera issue I think. When using flycapture it also crashes without any errors. According to Pointgrey it is a connection issue, but we could not completely solve it. Using different USB cables and making sure, that these are firmly attached can help.
