You can also have a look at this recent blogpost on debugging for more about the error handler and debugging. It is well worth a read-through.

If all the LEDs are lighting up then you are in the error handler because one of your calls returned a non-zero error code and APP_ERR_CHECK() calls the error handler and all the LEDs light up to tell you this fact so you can go and debug. Get the debugger out, put a breakpoint in the error handler, or wait until all the LEDs light up and hit 'break' and look at the stack trace to see where you are and what call failed and what the error code was which caused it.

If you're using some hard-coded delay then you're most likely already doing something wrong, hard-coded fixed delays are almost always a hack which hides a real issue.
