Hi, currently we deploying Dovecot as imap/pop3 proxy. Every few minutes some panic/assert occurred (we connect roughly 7k - 8k user at one imap proxy with a connection rate of 200/s). We activate core dumps. Concerning the sensitive information in the dump we would prefer to not share the dump (e.g. i found our ssl private key in the dump).
