> Thanks for Dmitry and Anthony's help, But my problem is not like Dmitry
> said.
>
> My program is a esl client. The leak is from esl client, not freeswitch.
>
> I add the Anthony's patch code into esl.c,but it doesn't work. Each call
> will cause the 20-40KB of memory growth.
>
> I make 3 calls, the valgrind outputs like this
>
> ==14459== 90,642 (264 direct, 90,378 indirect) bytes in 3 blocks are
> definitely lost in loss record 403 of 408
