svnsync: Authorization failed

Hi,

I got the following error when I ran svnsync:
[root_at_zch124svn01 conf]# svnsync sync svn://zch124svn01.ap.mot-mobility.com/miracle3
...
subversion/svnserve/serve.c:167: (apr_err=170001)
svnsync: Authorization failed

but I can co or export it with the same user, e.g.
[/dept/stb/...67/svn/test]$ svn export svn://zch124svn01.ap.mot-mobility.com/miracle3
A miracle3
...

Below is my system info:
[root_at_zch124svn01 conf]# cat /etc/issue
CentOS release 6.4 (Final)
Kernel \r on an \m

[root_at_zch124svn01 conf]# svnsync --version
svnsync, version 1.6.6 (r40053)
   compiled Oct 24 2013, 13:59:58
...

BTW, we can sync it before rebooting the system, but after reboot it, we got this error. I start the service with this command:
svnserve -d -r /svn_files/svn/

Thanks,
Hubert Li
