[CentOS] strange 'find' tool behavior

Hi all,

Just encountered an strange bahavior of frequent 'find' command. I tried to use find to recursively remove .svn directories from my working place, 'find' command removed all the '.svn' directories successfully but reported errors on screen. Any one knows why it shows this behavior?

BTW, if I use command " find . type d -name '.svn' -print0 | xargs -0 -n1 /bin/rm -rf ", then it does the same job and reports no errors on screen at all. But still likes to understand why find have this behavior.

The screen and error prompts are attached below for your references. Thanks.
