dovecot - Jun 2006 - dovecot-1.0_beta9 : (auth) killed with signal 11

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

Hello,
I regret that _I_ don't have an answer. But wanted to mention that
I ran into _exactly_ the same situation with .99
I fought it for several days trying to DEBUG the cause for it.
But finally gave up out of frustration. I'm successfully
running 1.0b7 now. But will be watching this thread closely in
hopes to find what causes this.

Best wishes, and the best of luck to you.

Your main problem is that you're trying to use digest-md5 or cram-md5
with DES crypted (?) passwords. This won't work. Either you'll need the
password to be in DIGEST-MD5 crypted format (in which case CRAM-MD5
won't work), HMAC-MD5 crypted (in which case DIGEST-MD5 won't work) or
in plaintext (which has its own problems of course).

Whatever of those you use you'll have to prefix the password field with
{scheme}, like {DIGEST-MD5}123456.

The crash is a bug anyway, I'll fix it for next version.
