Hello Matteo,

Could you confirm what version of ejabberd your are using ? Did you install it with Linux installer or did you compile it ? Which version of Erlang are you using ?
Do you have a 2.4 kernel ?

We need more information to be able to help you.

Thank you !

What a coincidence: I am

What a coincidence: I am experiencing the same errors! :-)

At least it is not caused by high load. If I install the Linux installer on a (not up-to-date; it is for testing) Debian installation and replace the default configuration with this one:
this config file, I get the same errors when running ejabberdctl and connecting to the server is not possible.

If I change these lines in that config:

{access, announce, [{allow, direction},
      {allow, admins}]}.

Into this:

{access, announce, [{allow, direction}, {allow, admins}]}.

Then it works!

The strange thing is, is that I cannot reproduce the error on other systems when I do exactly the same (Linux installer, same config):

Not working systems:

Linux genesis 2.4.27-2-k6 #1 Mon May 16 17:10:52 JST 2005 i586 GNU/Linux

Working systems:

Linux atenea.pike 2.6.11-1-386 #1 Mon Jun 20 20:53:17 MDT 2005 i686 GNU/Linux
Linux levi 2.6.10-5-386 #1 Fri Sep 23 14:13:55 UTC 2005 i686 GNU/Linux

What is your system? Maybe Linux 2.4 is the delinquent...

You said on another thread:

I have a (too much) successful jabber server with ~7700 registered users, and ~600 peak concurrent connections each day.

And now:

it doesn't work anyway when exposed to the high load of the main server

It's strange that only 600 users can generate so many load. njs.netlab.cz has around 1100 concurrent users, gizmoproject.com 1800, jabber.ru 2000, and they work perfectly.

Have you verified that it works correctly if there is not load? After restart, for example.
Did you check CPU and MEM usage (the ejabberd system process is probably called 'beam')?
What are the system specs (CPU, amount of RAM, operating system/distribution)?
Did you take a look to the logs? Maybe there are ERROR REPORT or warnings.
