Hello, I just stumbled into this directory: /var/lib/cyrus/lock/ It seems to contain many dead things, like .lock-files that - based on their names - must be older than 2+ years, including .../user/$NAME where $NAME does not have a mailbox/account anymore. Is it safe to shut down cyrus and do a find /var/lib/cyrus/lock/ -mindepth 2 -delete Its currently cyrus 3.0.13 on debian 10. br, Jan ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
