Hi all,<div><br></div><div>My FreeSWITCH setup works as follow: I have a service that launches and monitors faxes (via event sockets) on one of a few FreeSWITCH instances. These FreeSWITCH instances are running on dual-core, 2ghz CentOS 5.8 and CentOS 6.0 VMs. The issue is that once I get to ~200 simultaneous faxes on any one FreeSWITCH VM the load average shoots up (typically ~30, although I've seen it get much higher) and the VM becomes sluggish and occasionally unusable.</div>
<div><br></div><div>top and sar output confirms that CPU utilization is pretty low, as are IO wait and RAM usage.</div><div><br></div><div>I'm using a git head from 2012-02-06, although I see the same problem if update to a more current head. On the most recent head I tried (2012-08-06) the issue is worse, and crashes with a backtrace similar to this Jira, <a href="http://jira.freeswitch.org/browse/FS-2893">http://jira.freeswitch.org/browse/FS-2893</a> despite my compiling Lua and including the FreeSWITCH bindings.<br>
<div><br></div><div>These issues occur on both the CentOS 5.8 and 6.0 VMs. I'm in the process of loading 5.8 onto a physical machine and testing there. It's also worth nothing that this load issue does not occur when I launch faxes from a script on one of the VMs.</div>
<div><br></div><div>Has anyone else seen similar high load issues before?</div><div><br></div><div>Many thanks,</div><div>Adam Johnston</div></div>
