<html><head></head><body>I did try to change the service names. I posted that result to the group. It did not make a difference.<br>
<br>
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>

The problem is that I can connect to cyrus listener on all<br /> ip/ports for all domains, but while one of them will fork immediately<br /> and respond with a banner, the others will delay for a period of time<br /> from a few seconds to a minute or so before forking and responding with<br /> a banner. With the same setup, I change to a single threaded cyrus<br /> server to listen on all ip/ports then I get an immediate response on<br /> all, but of course I do not get the separate tls certificate or<br /> configuration. It is replicable that switching between the single<br /> threaded and multiple threaded configuration triggers the problem. I<br /> have searched the logs and the mail-lists and found nothing that seems<br /> related.<br /> <br /> Question: why does switching to multiple threaded cyrus server trigger<br /> delayed forking of imapd processes after connecting to master listener?<br /> <br /> On listener which responds immediately (as expected) I get this:<br /> <br /> user@somehost:~> telnet <a href="http://imap.domain1.com">imap.domain1.com</a> 143<br /> Trying <a href="http://192.168.110.171">192.168.110.171</a>...<br /> Connected to <a href="http://imap.domain1.com">imap.domain1.com</a>.<br /> Escape character is '^]'.<br /> * OK [CAPABILITY IMAP4rev1 LITERAL+ ID ENABLE STARTTLS AUTH=GSS-SPNEGO<br /> AUTH=GSSAPI AUTH=DIGEST-MD5 AUTH=CRAM-MD5 AUTH=LOGIN AUTH=PLAIN SASL-IR]<br /> <a href="http://imap.domain1.com">imap.domain1.com</a> Cyrus IMAP v2.4.18 server ready<br /> <br /> On listener with delay, I get this (and process hangs for many seconds<br /> or even a minute or two):<br /> <br /> user@somehost:~> telnet <a href="http://imap.domain2.com">imap.domain2.com</a> 143<br /> Trying <a href="http://192.168.110.171">192.168.110.171</a>...<br /> Connected to <a href="http://imap.domain2.com">imap.domain2.com</a>.<br /> Escape character is '^]'.<br /> <br /> The domain for which the listener responds and the one for which it<br /> delays seems to change and be random as far as I can tell.<br /> <br /> There is nothing </blockquote></blockquote></blockquote></blockquote></pre></blockquote></div><br>
