Hello list,
first I want to thank the developers for the great work they are doing
in creating and maintaining the sofia library.
But now to my problem:
I'm writing a SIP client application to run on an ARM platform and I'm
having serious problems with a memory leak in the sofia library.
It seems the memory allocated with nua_handle() is not freed if
nua_handle_destroy is called.
To demonstrate the problem, I appended the source code of a mini sofia
program which allocates a bunch of nua_handles, and after that destroys
them, but the memory is never freed (on ARM). On x86 the memory is
freed, but sometimes not immediately; sometimes it takes a couple of
minutes until the memory usage of the process gets back to normal (can
anybody explain this?). But on ARM the memory usage doesn't go back to
normal, even after hours the memory is not released.
I'v configured the sofia-library for arm using: ./configure --host=arm
--without-openssl --without-glib --prefix=/home/fsminimal/usr/local
where /home/fsminimal is my ARM root directory. I'm linking the static
library.
I had to undefine HAVE_CLOCK_GETTIME in the source, since
CLOCK_MONOTONIC is not supported on my ARM system. For comparison I even
undefined HAVE_CLOCK_GETTIME for the x86 platform but it didn't have any
negative effect there.
Besides this, sofia is working as it should, but the memory consumption
of my application is steadily increasing (during a load test), until the
process is killed by the OOM .
Does anybody have an idea what is causing this?
Thank you in advance for your answers,
Friedrich
