Hello,<br>
<br>
MEMDBG=0 turns on f_malloc, disabling q_malloc. The token F_MALLOC
in the kamailio -V output shows f_malloc is in use.<br>
<br>
q_malloc is more suitable for debugging, as it keep trace of
location in the source code that allocates/frees the memory chunks,
at the expense of a bit more memory usage due to tracking overhead.
q_malloc was the default for 3.1, that's why I asked because the
trace showed lines from f_malloc c code.<br>
<br>
What is the size of shared memory you start kamailio? Is the default
32MB or you give a different -m parameter value? Was the serve very
loaded? How many such situations did you get so far?<br>
<br>
Cheers,<br>
Daniel<br>

I observed two

<br>
I don't know
exactly what
may be caused
this core
because the
debug of
kamailio is
disabled, but
looking at
backtrace
(gdb) and
source code I
could notice a
relationship
with TLS
connection
establishment
(handshake).
Other
important fact
is that core
was generated
by the kamalio
itself with
signal 6
(abort)
because it
can't find the
pointer to
memory
realloc.<br>
I'd like to
know if
someone
already
observed this
issue and if
my analyse
above is
correct?<br>
