<div>Hi all,<br>
<br>
I observed two at 0x08173bf0 in fm_realloc
(qm=0xb5f7d000, p=0xb61f0bc0, size=0) at
mem/f_malloc.c:536.<br>
<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>
<br>
Bellow is backtrace full with gdb:<br>
<br>
Core was generated by
`/home2/local/kamailio/sbin/kamailio -P
/var/run/kamailio.pid'.<br>
