Sorry To Revive A Old Thread.<br><br>But this could be interesting for some :<br><br>Problem :<br>I started to get some signaling problems with some calls :<br><br>The SIP trunk was passing me 180 Ringing but the local station was not ringing , after a wire shark sniff i noticed that packets were coming out of order.<br>
Before calling our ISP , i used wire shark on the FS Public Interface , and the packets were coming in the correct order but FS would take up to 5 seconds to route them into the private network and would mix the signaling.<br>
So debug started , there was lots of CPU + Memory , IO was not a problem , network was also fine with 0 packet loss .<br><br>So i turned into FS , i noticed this happened on a specific call volume , after reading and reading i noticed a line in the wiki stating that libsofia profile is single threaded .<br>
<br>Solution :<br><br>Start Another Profile on a different port Ex: 5081 and route your calls trough that profile i noticed an improvement right away.<br><br>originate sofia/2_profile/XXXXXX@mygatewayip<br><br>Now i'm using profiles to load balance calls inside FS.<br>
<br>P.S - I know this can be pretty obvious for some but some of us are still new to FS so i hope this can help someone out :D.<br>P.S2 - Also if a veteran thinks this is the wrong approach please respond so we can all improve.<br>

<br>
We had high CPU utilization peaks in the past, which lead to some audio<br>
issues (clipping). We were using debian at that time, which was a<br>
customer-side requirement.<br>
<br>
I'm not a kernel guru but I remember this had something to do with kernel<br>
timer cycles and the issue was address by adding "divider=10" or<br>
"divider=100" as a kernel's boot loader option.<br>
<br>
My 2 cents,<br>
