Daniel, I don't remember to enable f_malloc... Actually I do not know the difference between f_malloc and g_malloc to choose compile kamailio with f_malloc instead of g_malloc.
My commands to compile kamailio were:
$ make PREFIX="/home2/local/kamailio" FLAVOUR=kamailio include_modules="db_postgres tls" MEMDBG=0 cfg
$ make all
$ make install
If you need more informations, I am available...
Best Regards
Hello,
can you provide output of 'kamailio -V'? Did you enable f_malloc instead of q_malloc which was default in 3.1?
Cheers,
Daniel

Hello,
it is in my to-do list to investigate, so far I was not able to reproduce.
Vacation time together with other travelings makes a bit more slower process. Please add it also to the tracker:
http://sip-router.org/tracker/
A minor release for 3.3 branch is going to be soon, being there makes sure it will be reviewed to see if it applies.
Cheers,
Daniel

Hi Users,
This is my ultimate try to ask for some help to debug the two cores generated by fm_realloc() function. If somebody can give me a feedback about my questions or doubts I will be very grateful, this user list of kamailio always help me to solve my problems.
Best Regards

Hi All,
I imagine that this core doesn't easy to replicate but somebody can help me to understand why it was generated? There is some way to prevent it?

I am having the same problem on kamailio 3.1.6. Someone please help.

Hello,
send also the version 'kamailio -V' to match the proper sources.

Hi all,
I observed two at 0x08173bf0 in fm_realloc (qm=0xb5f7d000, p=0xb61f0bc0, size=0) at mem/f_malloc.c:536.
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.
I'd like to know if someone already observed this issue and if my analyse above is correct?
Bellow is backtrace full with gdb:
Core was generated by `/home2/local/kamailio/sbin/kamailio -P /var/run/kamailio.pid'.
