Hi all We have Samba PDC with OpenLDAP (samba 3.0.21c openldap 2.3.19) . we have another linux system which is acting as Domain member server( samba 3.0.21c) . On the domain member server we have declared some shares which get mapped to my win2k clients as drives. when client access the share declared in Domain Member Server, the samba creates smbd process by the user id After client closes the shares and logs off , the smbd process created by that users still exists and never gets killed and about 100 smbd process are getting created there by samba getting hanged and unable to process the client requests. The following is the ps -aux | grep smbd | grep testuser output of smbd process by a user named "testuser" ############################################################################################### testuser 12844 0.0 0.4 14804 4696 ?
