What rate do you see your cron handlers fail? You mention that your cron jobs fire off once every five minutes which is 288 per day. Of these, how many fail? Do you notice any patterns, e.g. consistent failures at a certain time of day or multiple failures in a row? Any specifics you can provide would be helpful. Also, please provide your runtime (Python or Java) and app ID.
