[Freeswitch-users] FreeSWITCH 100% CPU utilization

Sun Apr 9 05:50:33 MSD 2017

What can happen is that the incorrect info can also get archived and its
hard to undo so there is a similar duty to debunk anything that may lead to
confusion for those who read it in years to come.  Maybe supply the wiki
page you saw that on and we can correct it.  Hopefully its on the old wiki.

We can't do much to debug 1.2 so you are correct.  We will have to update
to latest to get any clean idea of what you problem is.  (If it persists)
Rest assured that a properly functioning FS will do its best to distribute
the load across all CPU when it can.
