[Freeswitch-users] CPU sys load issue

Yes, to clarify the sync_clock was a different issue it appear in this 
tread to discard that could be the cause behind from the main problem on 
cpu peaks, and it doesn't.

My initial problem off cpu peaks, the main reason behind looks like that 
malloc calls are locking the cpu after a while  of running fs, or 
something is triggering block in fs.
I've putt all the info in jira, I'm still searching and trying to 
reproduce the issue in a local machine.

using tcmalloc implementation solves the issue, and so far as been quite 
mornings. :)

Regards,
António
