<p>Hi all,</p>
<p>thanks a lot for all hints and discussion.</p>
<p>I still do not have a finally correct answer to my problem. But I
found some interesting things about my dovecot installation. First
it is running without any problem once built with
--with-ioloop=poll. What I found during my further investigations
on this topic is that with epoll I get regular log entries like
(every minute):</p>
<p><font face="monospace">Feb 9 22:36:42 mail dovecot: [ID 702911
mail.crit] anvil: Fatal: epoll_create(): No such file or
directory<br>
Feb 9 22:36:42 mail dovecot: [ID 702911 mail.error] master:
Error: service(anvil): command startup failed, throttling for
60.000 secs<br>
Feb 9 22:36:42 mail dovecot: [ID 702911 mail.error] imap-login:
Error: read(anvil) failed: EOF</font><br>
</p>
<p>Built with poll I don't get this log entries. anvil is a default
service which I did not change at all. That means anvil is running
configured by default with chroot=empty. According to dovecot
documentation:</p>
<p><code class="docutils literal notranslate"><span class="pre"><span
class="highlighted">doveadm</span></span> <span class="pre"><span
class="highlighted">who</span></span></code><font
face="monospace"> and some other <span class="highlighted">doveadm</span>
commands connect to anvil’s UNIX listener and request its state.</font></p>
<p>And this works too without problems in my environment, which is
another proof that everything is ok. My current conclusion is that
executing /usr/libexec/dovecot/anvil is not working because it is
not meant to run standalone. Of course this should be covered,
too. As already mentioned my dovecot setup is running within a
separate zone. But I've not explicitly configured any chroot
setting.</p>
<p>So, definitely dovecot refuses to work correctly if built with
epoll. But of course all my tests are by far not exhaustive but
I'm pretty confident that the package I built is doing its job
flawlessly.</p>
<p>cheers,</p>
<p> Fritz</p>
<p>PS: further comments of course welcome ;-).<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>
