Hi, I tried to performance test freeswitch with media proxy thur fs. With 400 cps, I start to see 2000 channels remaining in Freeswitch, and then "no read codec" error starts to pop up. With only 1875 channels, how come freeswitch is complaining about no read codec? Also, I am using media_proxy = true, whey should it need a codec anyway? freeswitch@mycom.com> 2009-09-14 20:59:16.777675 [ERR] switch_core_io.c:118 sofia/external/12323232@192.168.1.116:5911 has no read codec. 2009-09-14 20:59:30.815547 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. 2009-09-14 20:59:30.815547 [ERR] sofia_glue.c:2566 AUDIO RTP REPORTS ERROR: [] 2009-09-14 20:59:45.349181 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. 2009-09-14 20:59:45.350179 [ERR] sofia_glue.c:2566 AUDIO RTP REPORTS ERROR: [] 2009-09-14 21:00:00.104559 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. 2009-09-14 21:00:04.495545 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. 2009-09-14 21:00:16.996438 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. 2009-09-14 21:00:25.905617 [ERR] switch_core_io.c:118 sofia/external/ 12323232@192.168.1.116:5911 has no read codec. freeswitch@mycom.com> show channels count API CALL [show(channels count)] output: 1875 total. freeswitch@mycom.com> 2009-09-14 21:00:36.212767 [ERR] switch_core_io.c:118 sofia/external/12323232@192.168.1.116:5911 has no read codec. After I paused the traffic from sipp and when sipp finished, I still got a bunch of zombie channels that are in CONSUME_MEDIA stage.
