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.

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?

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'.
