Re: [SR-Users] Core fm_realloc function

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 2012/7/23 Bruno Bresciani &lt;bruno.bresciani(a)gmail.com <mailto:bruno.bresciani@gmail.com>> 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? Best Regards 2012/7/18 Renan Capaverde &lt;renan.capaverde(a)digitro.com.br <mailto:renan.capaverde@digitro.com.br>> I am having the same problem on kamailio 3.1.6.
