I have just upgraded from courier to dovecot and things seem to be working okay (after a few problems getting shared folders working correctly).

I notice the following error message in my logs:-

Jun 23 11:17:32 calzone dovecot: child 1258 (auth) killed with signal 11

I am using the beta9 ebuild that is available from gentoo portage. I have followed the steps to try to get a core dump but it doesn't seem to be working.

My config file is as follows:-

=============================================================== protocols = imap imaps

protocol imap { listen = 127.0.0.1:143 ssl_listen = *:993 }

mail_drop_priv_before_exec = yes auth_debug = yes #mail_debug = yes

default_mail_env = maildir:/var/spool/mail/virtual/users/%u

auth default { mechanisms = plain digest-md5 cram-md5

userdb passwd-file { args = /etc/imap.passwd } passdb passwd-file { args = /etc/imap.passwd } } namespace private { separator = . prefix = Inbox. inbox = yes }

namespace public { separator = . prefix = Allstar. location = maildir:/var/spool/mail/virtual/users/shared::CONTROL=/var/spool/mail/virtual/control/%u:INDEX=/var/spool/mail/virtual/control/%u }

All users use UID/GID 5000.

/etc/imap.passwd contains enteries such as:-

paul:rMPY999gvr2kU:5000:5000::/var/spool/mail/virtual/users/paul

Any advise on how I can produce a core dump and get this fixed?

Thanks

Paul
