Title:
  OOM using CRON but not using SHELL under 16.04

Status in cron package in Ubuntu:
  New

Bug description:
  When I start a java program with high memory usage ("-Xmx52g") by
  shell, everything is working well. However if I start the same program
  with the same command and same user by CRON, I get a
  java.lang.OutOfMemoryError just after a few seconds.

  Additionally CRON isn't able to do anything as long as I don't kill
  the blocked java program. No matter which cronjob should be started,
  it always ends up with "(CRON) error (can't fork)" in syslog. After
  killing the java program all new cronjobs are working fine again.

  The problem only occurs with Ubuntu 16.04, all older versions worked
  very well.
