<br>
That "error" is most likely due to out-of-dialog ACKs to 487
responses (CANCEL scenarios). Thank you for reporting - it
should actually be a debugging message.<br>
<br>
Best regards,<br>

First of all, are you using the async_tcp option in
your OpenSIPS script ?<br>
Also, what architecture / OS are you running on ?<br>
What steps are you taking in reproducing this ?<br>
<br>

That bug log actually says OpenSIPS

I will look into that. What exact
version do you use (opensips -V) ?
also, can you reproduce this bug ?<br>

<div class="moz-cite-prefix"><tt>Hi,<br>
<br>
Those messages say that
OpenSIPS tried to open a
TCP connection to a
party which does not
respond -> there was
a timeout for connect in
10 seconds. Because of
this blocking in
connects, there were not
more opensips workers
available to handle
other traffic.<br>
<br>
So what you need to do
is :<br>
- minimize the
impact of the blocking
connect - see my
previous email on
reducing the connect
timeout<br>
- you may configure
OpenSIPS not to open new
TCP connect (but to
reuse the existing ones,
open by clients). See
tcp_no_new_conn_bflag<br>

target="_blank">http://www.opensips.org/Documentation/Script-CoreParameters-1-11#toc96</a><br>
- try to understand
the SIP patterns where
such TCP connect fails
so you can avoid them at
script level.<br>
