<br><h2>iax.conf
</h2>The new threading model is great, but the default of 10 threads is
way too low. Symptoms include total loss of audio until the channel is
hung up.

<br>that gets the current load from a monitoring machine and then changes the<br>priority. Dialplan snippet:<br>----------- Snippet -----------<br>exten => _X.,1,AGI(manager.agi)<br>exten => _X.,100,Dial(IAX2/asterisk1/${EXTEN})
<br>exten => _X.,200,Dial(IAX2/asterisk2/${EXTEN})<br>exten => _X.,300,Dial(IAX2/asterisk3/${EXTEN})<br>exten => _X.,400,Dial(IAX2/asterisk4/${EXTEN})<br>exten => _X.,500,Dial(IAX2/asterisk5/${EXTEN})<br>----------- Snippet -----------
<br><br>This works fine for a few calls. I'm using the SIPp package to generate a<br>10-25 simultaneous call load. Every once in a while I starting seeing loads<br>of error messages on AsteriskM's console:<br><br>
chan_iax2.c:7054 socket_process: Peer 'asterisk4' is now UNREACHABLE! Time:<br>2<br>chan_iax2.c:6216 socket_read: Out of idle IAX2 threads for I/O, pausing!<br>chan_iax2.c:909 __schedule_action: Out of idle IAX2 threads for scheduling!

<br>scroll very quickly. If I give the system a minute everything goes back to<br>normal.<br><br>I would like some one who is very knowledgeable about IAX to assist me with<br>this problem. If someone knows a lot about IAX optimization and is willing
<br>to work with me I would be willing to pay for their time.<br><br>Thanks,<br><br>David Ruggles<br>CCNA MCSE (NT) CNA A+<br>Network Engineer Safe Data, Inc.<br>(910) 285-7200 <a href="mailto:david@safedatausa.com">
