The controller is not is a 'bus off' state. Another page used as transmitter is still working fine. It seems that just one page does not transmits its content. When I change the page for this message, it has the same problem. Therefor I presume it is not page related.
The weird thing is that the controller functions for some time normally, and suddenly (haven't figured out exactly when) a page stops transmitting. The remaining (programmed) pages also remain functional as receivers.
