Have you followed all instructions here: http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations#FreeSWITCH.27s_core.db_I.2FO_bottleneck ?

Have you set logging to a reasonable level?  What does top or htop say?  How is the machine configured (CPU / RAM / HDD subsystem) ?

What are you doing after the calls are connected?  What other software is running on the same machine?

Regards,

Guillermo

You don't mention the version of FS or the specs on the machine.

Have you tried asking Sangoma for ideal setup for your needs or for support?

We are having two (Sangoma) Voice Cards, one with 8-ports and other with 16-ports.

I have integrated ESL library with java in INBOUND MODE and making outbound calls.

The issue what we are facing are
1. When I use all 720 channels or more than 450 channels, we see the events processed by ESL is very slow and we are not getting the events properly from ESL after placing the calls, even after so many minutes, so we have to forcefully close the connection.

2. And I see error mod_event_socket.c:375 Lost 502 events!
And the java app also crashes with error ESL connection timeout.

3. And I see segmentation_fault in Freeswitch and big dump file is written and which would crash the system, because of high CPU\IO.
But if we reduce the channels say, 450 we don't see any issue at all.

What could be the reason for this issue.

Appreciate any Help...
