I am using Debian 7 and the CPU usage shows very high. Adding <span style="background-color: rgb(0, 0, 0); color: rgb(255, 255, 255); font-family: 'Andale Mono'; font-size: 12px;">nohz=off</span> to grub options does makes it lower. I am gathering more information in order to file a Jira. Debian 6 on the other hand works very quietly on the same workload. We are talking about 200+% CPU utilization on Debian 7 and around 50% on Debian 6 showing in htop. I know so many other factors also involved but I am still digging out more.</div> <br> <div id="bloop_sign_1423657964228882944" class="bloop_sign">—<div>Thanks,</div><div>Muhammad Naseer Bhatti</div></div> <div style="color:black"><br>From: <span style="color:black">彭勇</span> <a href="mailto:ppyy@pubyun.com"><ppyy@pubyun.com></a><br>Reply: <span style="color:black">FreeSWITCH Users Help</span> <a href="mailto:freeswitch-users@lists.freeswitch.org"><freeswitch-users@lists.freeswitch.org>></a><br>Date: <span style="color:black">February 11, 2015 at 3:20:46 PM</span><br>To: <span style="color:black">FreeSWITCH Users Help</span> <a href="mailto:freeswitch-users@lists.freeswitch.org"><freeswitch-users@lists.freeswitch.org>></a><br>Subject: <span style="color:black"> Re: [Freeswitch-users] Freeswitch 1.4.15 and a sudden jump in CPU usage <br></span></div><br> <blockquote type="cite" class="clean_bq"><span><div><div></div><div>same issue.<br><br>I have several FS 1.4.15 running on CentOS 6.5 x86_64, the CPU will be<br>very high about 9:00 am every morning. there is no crontab at this<br>time.<br><br>i will downgrade to 1.4.14 to see if there is such issue.<br><br>On Wed, Feb 11, 2015 at 1:14 AM, Ali Pey <alipey@gmail.com> wrote:<br>> Hi Anthony,<br>><br>> I do not know if I am hitting a bug and if this is a bug, I don't have much<br>> info.
