what it shows. Is there anything here that should limit cyrus?</p>

I am not a low-level programmer so maybe have the wrong idea here,
but it seems locked on reading the imapd executable. Doesn't that
suggest a system limit of either open files or open processes? I
have tried to open up those limits as it was my first angle of
investigation. What confuses me is that the problem goes away when
I switch to a single-threaded Cyrus service listening on all ports
simultaneously.<br>
<br>
Any thoughts, suggestions welcome. <br>

<pre class="k9mail">well, it tells us that it has to do with locking during connection accept.
have you tried to use different service name per server as was suggested by
others?

trace. you will have to "catch" the process that blocks. it may not be
easy, but I have no other suggestions.

I am not sure how to run strace on the process that the Master listener
forks. Here is the strace run on the imapd process at a command prompt
(which is not quite the same as the master listener forking it to a port
where another process is waiting to connect to it).

Subject Re: Multi-thread cyrus delayed forking of imapd processes after
connecting to master listener
My immediate guess is it blocks at reading /dev/random.
strace should show you exactly where it blocks.
What version of SASL are you using? Newer versions have switched to
/dev/urandom AFAIK

<blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #fcaf3e; padding-left: 1ex;"> Apologies for long post, most of it is configuration details.
I have recently changed from a single threaded cyrus server in which
multiple domains were overloaded on one listener as multiple virtual
domains to a multiple threaded cyrus server in which multiple domains
are listened for on separate ip addresses with separate configurations.
The primary motivation was to have separate tls certificates for each
domain. The problem is that I can connect to cyrus listener on all
ip/ports for all domains, but while one of them will fork immediately
and respond with a banner, the others will delay for a period of time
from a few seconds to a minute or so before forking and responding with
a banner. With the same setup, I change to a single threaded cyrus
server to listen on all ip/ports then I get an immediate response on
all, but of course I do not get the separate tls certificate or
configuration. It is replicable that switching between the single
threaded and multiple threaded configuration triggers the problem. I
have searched the logs and the mail-lists and found nothing that seems
related.
Question: why does switching to multiple threaded cyrus server trigger
delayed forking of imapd processes after connecting to master listener?
On listener which responds immediately (as expected) I get this:
user@somehost:~> telnet <a href="http://imap.domain1.com" moz-do-not-send="true">imap.domain1.com</a> 143
Trying <a href="http://192.168.110.171" moz-do-not-send="true">192.168.110.171</a>...
Connected to <a href="http://imap.domain1.com" moz-do-not-send="true">imap.domain1.com</a>.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE STARTTLS AUTH=GSS-SPNEGO
AUTH=GSSAPI AUTH=DIGEST-MD5 AUTH=CRAM-MD5 AUTH=LOGIN AUTH=PLAIN SASL-IR]
<a href="http://imap.domain1.com" moz-do-not-send="true">imap.domain1.com</a> Cyrus IMAP v2.4.18 server ready
On listener with delay, I get this (and process hangs for many seconds
or even a minute or two):
user@somehost:~> telnet <a href="http://imap.domain2.com" moz-do-not-send="true">imap.domain2.com</a> 143
Trying <a href="http://192.168.110.171" moz-do-not-send="true">192.168.110.171</a>...
Connected to <a href="http://imap.domain2.com" moz-do-not-send="true">imap.domain2.com</a>.
Escape character is '^]'.
The domain for which the listener responds and the one for which it
delays seems to change and be random as far as I can tell.
