I would not use Linode, it adds a layer of uncertainty, because most of voip (and freeswitch) deployments are on actual metal hardware, and any additional layer will distance your install from mainstream.

Also, definitely not use Ubuntu. Use Debian 8 instead.

Also, consider moving to FreeSWITCH 1.6, 1.4 is rapidly approaching end-of-life.

That said, (and I strongly suggest you go to real hardware, Debian 8, FS 1.6 if you want things to go smooth), if you really want to do the investigation, this page can help you: https://freeswitch.org/confluence/display/FREESWITCH/Troubleshooting+Debugging

Consult http://confluence.freeswitch.org for information on how to debug, and *particularly* on how to report a problem/bug.

Hi,

My FS freeze with 100% CPU rate frequently. When it happens, there is no strange network traffic and no log at all. The last thing logged is just the processing of a normal phone call. Then everything stopped. How can I debug or find any clue about this issue? Thanks.
