After my software has been running for about 24 hours I suddenly get a blank LCD with BUFFER OVFLW on the top left.
The main code is still running. In fact, all threads are still running as I can breakpoint into them and step so I know they are all working. Wifi is still working, serial to both the modem and Zigbee are still working.
It messes up the dislplay as it keeps clearing to show the error. All the graphics get drawn on the display except the background is now black.
Lastly, if I breakpoint the code, the error continues to refresh on the LCD so it has to be coming from outside my code.
Anyone have any clue as to were this error originates from?
