> Can you show the output of /proc/rtcan/devices and /proc/rtcan/sockets > before and after the problem showed up. Below is an accumulation of what I think you are asking for. I am not convinced that the rtskb allocation failed message is serious, as you will see from the syslog and my comment above it only takes place when i close my application. Although I try to close all connections neatly certain threads still seem to be busy. See the errors I get on closing the application.
