When I don't specify an IP address, cyrus-imapd starts correctly on a

When I specify IP / protocol:
imap cmd="imapd" listen="192.168.1.230:imap" prefork=5 proto=tcp4
cyrus-imapd tries to bind to those before it is available, and fails:
Mar 20 20:53:31 emp87 cyrus/master[973]: unable to bind to imap/ipv4
socket: Cannot assign requested address
Mar 20 20:53:31 emp87 cyrus/master[973]: unable to create imap listener
socket: Cannot assign requested address
While thinking about it again, wouldn't it make sense to make master a bit
more robust so that it tries to start a service if it failed before, as
part of its maintenance functionality?
Depends if restarting is making things worse it's not always the correct thing
to do. You can change the systemd config to always restart it but this sort of
fix is always because of another underlying problem and not a good sign.
I'm old and not the biggest systemd fan or biggest knowledge about it.
It is interesting seeing this thread. I can not see why cyrusd would not
depend not network and FS to be up or any email service not depending
on these 2 things working.
Simon L.,
While I'm sure Simon M. can speak for himself, I'll pipe up here. I
believe what he was saying is that 'master,' now known as 'cyrmaster,'
the Cyrus super-daemon, should periodically try to restart any listener
sockets called for in the SERVICE section of cyrus.conf if which fails
to start in the beginning (assuming 'prefork' > 0).
I wholeheartedly agree with this idea.
Simon M.,
Are you submitting a feature request to the Cyrus team for this? If
not, I'll be happy to do so. It's a capital suggestion.
Cheers,
