Hi, I have a problem with a single mailbox. The user's Outlook crashed and since then the sync_client is running wild on this user account and produces high load on the master. I stopped sync_client on master side for the moment. When I try to sync the user by hand /bin/su - cyrus -c "/usr/lib/cyrus/bin/sync_client -S replicaserver -v -u testuser I do get the following error. Dec 11 17:54:48 master cyrus/sync_client[22727]: RENAME received NO response: Operation is not supported on mailbox Dec 11 17:54:48 master cyrus/sync_client[22727]: do_folders(): failed to rename: user.elsa-secgen -> user.testuser.Archives.Gesch&AOQ-ftsjahr 2014-15.25-Jahr-Feier Dec 11 17:54:48 master cyrus/sync_client[22727]: IOERROR: The remote Server(s) denied the operation Dec 11 17:54:48 master cyrus/sync_client[22727]: Error in do_user(testuser): bailing out! Comparing master and slave on filesystem I do see the subfolder "25-Jahr-Feier" in "user.testuser.Archives.Gesch&AOQ-ftsjahr 2014-15.", but only on master but not on slave side. And why does sync_client want to rename and where does it get this order from? I can login into the users' mailbox on master side and new message are shown in the INBOX. How can I fix it? Should I try a "reconstruct -r user.testuser" on master and slave or just on slave? (do I have to shutdown cyrus for a reconstruct -r on a user box?) Or can I delete the complete mailbox on slave side start an "sync_client -S replicaserver -v -u testuser"?
