Hi,

i've just upgraded to dovecot-1.2.8 (from 1.2.4) and do now get the following errors when deliver gets hands on mails with some attachments.

# tail -n 1 /var/log/messages Dec 14 19:00:36 mail3 dovecot: deliver(user): Panic: file istream.c: line 96 (i_stream_read): assertion failed: (stream->eof)

Can you reproduce this easily? Can you get it to dump core?

Happens everytime one tries to send mails which are slightly bigger (around 100k).

kern.corefile and kern.sugid_coredump sysctls probably help. I'd like to get at least gdb backtrace and also a few other variables.. http://dovecot.org/bugreport.html

Here's the backtrace and the output of dovecot -n. This is still 1.2.8, I will upgrade as soon as the new FreeBSD port is out there. The configuration is basically postfix with deliver as LDA and dovecot-sieve inside a FreeBSD 7.2 jail and maildir's on NFS.

thanks and happy holidays to everyone, Leon
