I have a script to start an ntp daemon in /jffs/etc/config/9ntpstart.startup.

When I run the script from the shell this works fine. However, when run from the system startup I this error is produced.

Code:

+ /opt/bin/ntpdate -t1 -p3 192.168.2.1
<jemalloc>: Cannot allocate memory for MADV_DONTNEED check
Segmentation fault
+ sleep 3


The script is simple:
Code:

#!/bin/sh

exec > /tmp/debug_ntp.txt 2>&1
set -x


while ! /opt/bin/ntpdate -t1 -p3 192.168.2.1 ; do
    sleep 3
done
/opt/bin/ntpd -c /opt/etc/ntp/ntp.conf


What is the difference in the enviroment from the startup scripts and the shell?

LD_PRELOAD= /opt/bin/ntpd -c /opt/etc/ntp/ntp.conf
fixes it.

seems ntp doesn't like /usr/lib/libjemalloc.so
