cannot modify limit: Operation not permitted

ulimit -c unlimited
ulimit -s 102400

bash: ulimit: core file size: cannot modify limit: Operation not permitted
I also tried setting ulimit to 50000 and still got the same error.

$ ulimit -a

在/etc/security/limits.conf  加入  * soft stack 102400

改完之后重新登录就行
