above error is OK
and other issue: in init.rc, I changed the coredump file to sdcard as below:

    setrlimit 4 -1 -1
    write /proc/sys/kernel/core_pattern /sdcard/core.%e.%p
    write /proc/sys/fs/suid_dumpable 1

but it can not work.

Hi,
Did you check the permission of /sdcard? I created folder /data/coredump and give it proper permission to do so.

mkdir /data/coredump 0777 system system

I add below code：
chmod 0777 /sdcard
to give it proper permission.
as below:
    setrlimit 4 -1 -1
    chmod 0777 /sdcard
    write /proc/sys/kernel/core_pattern /sdcard/core.%e.%p
    write /proc/sys/fs/suid_dumpable 1
but it still can not work.
