Hi

I am trying to publish a CAN message at 100ms rate on to a topic using a timercallback function. I am running the code onboard a vehicle and I have a Ubuntu 16.04 machine with ROS Kinetic and has ros-canopen/socketcan_bridge package. I am using PEAK USB-CAN Interface. When I publish the message on sent_message topic, it is not being sent to CAN bus and ROS gives out an error message "Failed to send message.....". I suspected this could be due to CAN driver not being ready and I also see that the CPU/processor usage spikes when I run the node that does this publishing. My code is straightforward in the callback and should not typically consume lot of resources ( I have i9-6700HQ processor, 16GB RAM with GTX1070). Here is the error message. Can you please help?
