bind9 문제입니다....

named start시의 로그
May 20 16:03:47 localhost named: named startup succeeded
May 20 16:03:47 localhost named[2099]: no IPv6 interfaces found
May 20 16:03:47 localhost named[2099]: listening on IPv4 interface lo, 127.0.0.1#53

May 20 16:03:47 localhost named[2099]: running

정상적으로 잘 되는데,

named stop을 하면... 로그가 다음과 같이 발생되고...
멈춰지질 않습니다...
May 20 16:04:17 localhost named[2099]: app.c:561: unexpected error:
May 20 16:04:17 localhost named[2099]: isc_app_shutdown() pthread_kill: No such process

그래서 천상 named서비스를 죽일땐 killall named를 씁니다...

저 에러가 어떤 에러인지요? 당췌 이것저것 해보고, 검색해바도...

해답을 찾을 수가 없네요...

도와주세요...
