Hi,

I am running some stress testings on freeswitch. When the number of
RTP ports reached around 1248 - 1250, freeswitch starts to pop out "No
RTP ports available!" error:

2008-12-23 13:14:02 [CRIT] sofia_glue.c:562
sofia_glue_tech_choose_port() No RTP ports available!

OS is Centos 5.2 64 bits and freeswitch is compiled with ./configure
--64bit options . I also followed the wiki to maximize all my ulimit
parameters, but nothing works. Does anyone know why? Any help will
be greatly appreciated.

Here are my sys parameters:

How exactly are you load testing this? Can you provide us an example?
