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>
