Re: [SR-Users] Core fm_realloc function

My openSSL version is 0.9.8... According to http://openssl.6102.n7.nabble.com/Custom-free-routine-is-invoked-with-NULL-… this was working fine in 0.9.8. I was analysing the backtrace full with gdb and the line below shows that ptr was not a NULL parameter. #4 0x0051a87f in ser_realloc (ptr=0xb61f0bc0, size=32) at ../../mem/shm_mem.h:266 ptr=0xb61f0bc0 size=32 Now, I'm a little confused...the changes to allow freeing of NULL pointer to behave like standard free () function will take effect to prevent the bug FS#247?

What do you suggest Daniel? q_malloc is more suitable for debugging. The 'get_statistics all' command is avaliable by a specific module? I run 'kamctl fifo get_statistics all' and return '500 command 'get_statistics' not available' Do you have kex module loaded? What is the output of 'kamctl fifo which'? For while is impossible to start a new installation, first because I don't know how much time I will spend to port and second because I am involved with other developments and I have no time to make this. I know that 3.1 is no longer a official branch but now start a new installation it's very very difficult, my in intention is discover what caused the crash and if exists a way to fix or prevent it. Discovering may require additional patches, like more debug messages in the C code, that's why is better to start with the latest stable.

Probably the size of shared memory that I start kamailio is 32MB because I didn't gave a different -m parameter value, exist a command to verify this information? kamctl fifo get_statistics all and see the shared memory total value. It will be interesting to see available shared memory as well. At moment that crash happened, there were few registered users agents and were being made tests with register and calls with TLS protocol. I got only the two situations that I showed at first email. If you plan to start a new installation, I strongly recommend 3.3 branch, the code is more actual and easier to debug. 3.1 is no longer an official maintained branch, those being now 3.3 and 3.2. I'm looking at this issue to be sure it is no longer in latest stable.
