Hi all,
thanks a lot for all hints and discussion.
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):
Feb 9 22:36:42 mail dovecot: [ID 702911 mail.crit] anvil: Fatal:
epoll_create(): No such file or directory
Feb 9 22:36:42 mail dovecot: [ID 702911 mail.error] master: Error:
service(anvil): command startup failed, throttling for 60.000 secs
Feb 9 22:36:42 mail dovecot: [ID 702911 mail.error] imap-login: Error:
read(anvil) failed: EOF
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:
|doveadm who|and some other doveadm commands connect to anvil’s UNIX
listener and request its state.
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.
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.
cheers,
Fritz
PS: further comments of course welcome ;-).

Sent this already to dovecot mailinglist without response so far.
Maybe someone reading this list can help. Unfortunately it did not
show up during the test run of the package and I used earlier versions
without this problem.
Dear list,
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.
