We noticed on a production instance with a ~6GB logs.db database and about 8 months of data, that when the routine that removes old log entries (than three months), logs seem to stop being ingested and the CPU usage keeps constantly at 100%. The proposed fix, as discussed with @njean42 is to have the cleaning routine being executed more often, deleting small batches, to avoid blocking the main database writer thread. The issue was introduced on implementing #204. **Version number of controlcenter** Version: 1.9 **Postfix version** Use `postconf mail_version` to get postfix version Version: 3.4.1 **Golang version** Version: 1.17 **Which Operating System and version are you using?** OS: Manjaro
