Thermal problem in system with c-gstreamer and other code in c++ with dBus

in order to get functional whole linux system we are running into the issue with new board. regarding our board designer there are no changes between new and old design, but only additional adding of functionalities. Despite this the new system has the ability to freeze during operation with old dbus app and gstreamer app. As symptom we can observe, that CAN communication will interrupt in PCAN-explorer.

Can you give guidance on this? Much appreciated.

As subject, you mentioned “Thermal problem”, but some HW changes in new board.
Also “CAN communication will interrupt in PCAN-explorer.” is an issue on new board?
You may do the debug from HW first, or do the analysis with system logs to see if can find the clues.
