check error log for any details about the 503 error.
Same problem here with vBulletin. This 503 error only occurs with random files from different PHP POST request.
if it is random (no pattern), then it is not easy to catch. a good starting point is to look at the error log for any details about the error such as the url triggered the error and whether php crash before it finished, etc.
