Hi Peter, Anthony,
Kevin MATHY | Ingénieur VoIP
Thanks for your answers.
Indeed, if I wanted to increase the stack size, it was just because of the advices written on this wiki page : http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations
I'm just a bit aware of how works internally a Linux OS, and so I simply followed what was said on the wiki, thinking that it'll be OK.
But in fact, it's not...
Anyway, I'll follow what you said, and let the stack size value to 240k, as FS doesn't need to use more. Thank you for this information.
Otherwise, when I make a "top" on my system, I've got the following output :
Tasks: 138 total, 1 running, 137 sleeping, 0 stopped, 0 zombie

In which we can see that FS seems to use 25% of CPU ressources, but all CPUs seem to be around 7% used (all counted).
So my question is : which one is the real value about CPU percentage used ?
I'm remember that FS has a function to refuse new calls if a CPU used precentage threshold is reached, and I'd like to set this value as well as possible. And for that I have to know the real usage of my CPU by FS.
Thanks a lot for your help,
Bien cordialement,
Best Regards,

Stack size is how much ram is reserved per thread open. We only need 240k and you are offering to let it use 8 megs.--

_________________________________________________________________________Hi List,I'm trying to make my FS server more performant and reliable, and I found the FS's wiki page telling that I can change some "ulimit" values on my system, like the Stack Size.So, I've changed in the init script the "ulimit -s" value to 8192, but now when I start freeswitch I've got the following error message :Error: stacksize 8192 is not optimal: run ulimit -s 240 from your shell before starting the application.
auto-adjusting stack size for optimal performance...So when I check the status :freeswitch@10.84.9.41@internal> status
UP 0 years, 0 days, 0 hours, 0 minutes, 6 seconds, 661 milliseconds, 592 microseconds
FreeSWITCH (Version 1.3.17 git 16289ce 2013-03-14 03:24:25Z) is ready
0 session(s) since startup
0 session(s) - 0 out of max 30 per sec
1000 session(s) max
min idle cpu 0.00/100.00
Current Stack Size/Max 240K/8192KIt seems that the 8192 value isn't set and is rollbacked to 240...I've got exactly the same result when the init script is filled with "ulimit -s 240".Do you have any idea about how to have the stack size increased ?Thanks a lot,Bien cordialement,Best Regards,Kevin MATHY | Ingénieur VoIP
