DB2 big strange problem - database is returned to CIRCULAR mode but archive logs keep coming to old archive location

my DB2 database (v 9.7) is in Circular mode.

Current Logging Type:Circular

(USEREXIT) = OFF
(LOGRETAIN) = OFF
(LOGARCHMETH1) = OFF
(LOGARCHMETH2) = OFF
(LOGPRIMARY) = 10
(LOGSECOND) = 10
Path to log files: /home/ctginst1/ctginst1/NODE0000/SQL00001/SQLOGDIR/

I had old archive location /opt/IBM/archive and now my hard disk space is full 100% because I have over 500 logs in that location which I cannot find that is defined somewhere.

What is going on?Why archive logs keep coming to old archive log location?

This is really big problem for us I will be thankful for any help
