CentOS版本 cat /etc/centos-release
  CentOS Linux release 7.2.1511 (Core)

设置ulimit -c ulimited

依旧无法生成coredump文件，其中也检查了cat /proc/sys/kernel/core_pattern 及/etc/abrt/abrt-action-save-package-data.conf 设置。

网上报出类似错误[https://access.redhat.com/solutions/2181441]：

kernel: Process (abrt-hook-ccpp) has RLIMIT_CORE set to 1

Issue

• No core files after install of ABRT on a RHEL 7.2 system: core aborted

Have a tried a reinstall but without any success: same error in /var/log/messages and no core file in /var/tmp/abrt (or /var/spool/abrt).
