It talks about a failed code assertion so something went out of
expected bounds. Can you check if doevecot wrote something more
usefull to syslog? <br>
<br>
Here it just says "file %s: line %d (%s): assertion failed:
(%s)" <br>
But not the actual assertion failure message. <br>

But I can't tell if thats the panic or why dovecots panics here.

Dear list, <br>
<br>
I built a dovecot package for openindiana (which is a Solaris
derivative) from latest version 2.3.18. Everything compiles
and builds fine without any issue. Even subsequent
installation and startup of main dovecot process works as
expected. But execution of /usr/libexec/dovecot/anvil
immediately crashes. To get some more meaningful backtrace I
compiled with -g. Below some facts of my environment and a
backtrace. Maybe some of you are more familiar with this kind
of issue as I, and can give some hint or share ideas how to
nail down the problem. Or can it be a configuration issue? BTW
it is running in a so-called zone. And former versions, I
don't know exactly but I believe up to 2.3.17, did not show
this crash. <br>
