Short Description
In some cases, the
sasl_log
table can grow very large. The SQL eventclean_sasl_log
is scheduled to clean thesasl_log
table daily. However, if the table has many rows, this process can cause deadlocks, which may result in failed Dovecot authentication attempts.Affected Containers

What did you tested?
I inserted 200,000 rows into the
sasl_log
table and triggered the SQL event. During its processing, SMTP and IMAP logins failed, and Dovecot produced errors. To resolve this, I created a PHP script that runs as a cron job and clears the sasl_log table in batches. This approach allowed logins to continue while the table was being cleared.
