If the application code causes the application to terminate when there was an exception, then this status will show up in the application logs. If you have the logs drained to an external logging service, then look at the logs to find the root cause of the problem. Developers should log all the exceptions and stack trace so it's easier to debug issues in production.
The X in the error message could be an integer between 0 - 255 (unsigned char). If the application returns a negative integer, it will be converted to an unsigned char. This means that if X is 255, the app could have returned either -1 or 255, since they are both the result when interpreted as an unsigned char.
