Hello, We run a 5 instances dovecot cluster ondebian 11 virtual machines, a dovecot proxy,2directors and2dovecot backends. All dovecot instances run version2.3.20. We use a glusterfs mounted volume on the backends forthe mail storage. Our users all use thunderbird mail client and they do not report any issue with the imap service. Since we have configured the dovecot cluster we see multiple random imap crashes with signal 11 and timeout leaks in the logs on both the backends for multiple users.
Is this is a configuration problem or a bug with imapc or imap; I would appreciate if you could assist us to debug this further. A coredump is attached if it helps.
Thank you for reporting this, we'll take a look
