I imagine it all ended well, as I don't recall hearing complaints on quality. I have noticed the core dump issue mixed with * and SQL a few months ago. We had about 120-150 users in a conference, that seemed to be okay, heard a complaint about a periodic sputter in audio, but nothing to serious. Issues came once the call was done, ~150 users all hanging up at once. SQL was VERY upset with that, causing * to choke. Though I think it was how we handled the deployment to get it up quickly, and may have been able to prevent this, if tested better. <o:p></o:p></p><div><p class=MsoNormal style='text-align:justify'><br clear=all><o:p></o:p></p><div><div><div><p class=MsoNormal style='text-align:justify'><span style='font-family:"Courier New"'>Keith</span><o:p></o:p></p></div></div></div><p class=MsoNormal style='text-align:justify'><o:p> </o:p></p><div><p class=MsoNormal style='text-align:justify'>On Wed, Dec 18, 2013 at 10:46 AM, Tech Support <<a href="mailto:asterisk@voipbusiness.us" target="_blank">asterisk@voipbusiness.us</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-align:justify'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> How did the system behave with 244 calls? I’ve been able to make 1,024 concurrent faxes (which tend to use more resources than audio calls) in the lab. The problem I had was after the faxes were transmitted, things couldn’t keep up and kept dumping core. Two things were going on, (1) the CDR was written to MySQL and (2) a FastAGI script (I use the AGISpeedy PERL package) to write a log entry also to MySQL. I tried switching the CDR’s to sqlite and that seemed able to keep up, except that its concurrency issues were a problem. If MySQL is the problem, I could probably optimize it better, but it doesn’t explain the Asterisk core dumps. It might be related to the number of FastAGI scripts running, I’m not sure at this point.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-align:justify'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Regards;</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-align:justify'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>John </span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> <a href="mailto:asterisk-users-bounces@lists.digium.com" target="_blank">asterisk-users-bounces@lists.digium.com</a> [mailto:<a href="mailto:asterisk-users-bounces@lists.digium.com" target="_blank">asterisk-users-bounces@lists.digium.com</a>] <b>On Behalf Of </b>Keith Sloan<br><b>Sent:</b> Wednesday, December 18, 2013 10:10 AM<br><b>To:</b> bilal ghayyad; Asterisk Users Mailing List - Non-Commercial Discussion<br><b>Subject:</b> Re: [asterisk-users] Maximum number of users</span><o:p></o:p></p></div><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;text-align:justify'>The better question is, maximum number of users (IP Phones) can your hardware support.
