Hello,<br>
<br>
great that it was sorted out and it was not on Kamailio side :-)<br>
<br>
Also, glad to hear that async processing did increase capacity to
handle more concurrent calls, even it was causing troubles to other
applications ...<br>
<br>
Cheers,<br>

<div>My business partner that found the issue and has been
monitoring the problem has tracked down the issue. It turns
out that the features we implemented using the async module
were leading to more calls going on con currently (as they
were intended to) and this was causing and issue with voip
monitor. So the issue was not with the Async module.</div>

<div dir="ltr">Hi All<br>
<br>
We are trying to use the async module to to delay sending
a bye on from one end of the call to the other.<br>
<br>
We are using async_route(routename, seconds) to delay
the WITHINDLG route. The idea is that in the future we
want to be able to have our billing min duration enforced
(though currently we are having issues with the dialog
module that we are discussing in another thread).
<div><br>
</div>
<div>After running this on our deploy servers, the delays
before sending on the byes get longer and longer, and
then kamailio goes down. Then the receive udp buffer
fills up.<br>
<br>
We tried it with both 4 and 400 async workers, and it
made no difference.</div>

when this happens taken from voip monitor.</div>
