[Dovecot] 1.1r1: auth-worker(default): BUG: PASSV had missing parameters, sig11

[Adam McDougall]

I don't know how this happened.  I'm not sure if there is a coredump 
somewhere because
I don't know what user, and I have nothing for 'root' or 'dovecot'.  Any 
advice, or should
I make all my coredumps go to a central writable directory so I have 
better chance of
catching it if it happens again?  Is it maybe from someone connecting to 
postfix and causing
a SMTP-AUTH to timeout?  Although that is unlikely because users should 
not know how to
reach this server's SMTP ports. I cut most of the surrounding log 
entries below because they
seemed unrelated normal activity, but two of the lines below I left 
because of the timestamp.

socket:
    type: listen
    client:
      path: /var/spool/postfix/private/auth
      mode: 384
      user: postfix
      group: postfix
