How to read a FreeRTOS trace dump

I'm just starting to learn FreeRTOS and have set up the Posix/Linux simulator on my laptop. The Blinky demo works fine but the Full demo breaks after around 5000 ticks with the error Error: StreamBuffer - tick count 50000. The Demo file produces a trace dump when you exit the application but so far as I can see it is completely unreadable. It appears as seemingly random text characters as if I have the wrong encoding or an incorrect baud rate (if I was using a physical device). I can only assume that the dump files are not supposed to be viewed as a normal text file but I cannot find this in the documentation.

Thanks in advance

That is almost certainly a false positive error that will be due to running so many self monitoring tests at the same time - some of which assume one or more of their test tasks is the only task running at the highest priority. The trace comes from the Percepio tool, see https://www.freertos.org/trace
