Bug Description
Ubuntu 14.04.5 LTS, cron 3.0pl1-124ubuntu2
On a server with heavy cron use (a few thousand entries across cron.d / users, several runs per second, a few dozen forks running at any given time), cron will creep up in memory usage. Last I saw was 6GB RSS, at which point it will start doing:
Jul 6 07:01:27 host cron[21699]: (CRON) error (can't fork)
Not all runs will fail, but this trend will continue until cron is restarted.
