[OpenSIPS-Devel] Help need to understand the memory log

[Răzvan Crainea]

Hi, Surya!

The memory log shows all memory chunks that have been allocated, and the 
function that allocated them. Therefore, in order to check for memory 
leaks, you need the entire information.

Let's take for example one entry:
        0. N  address=0x7febb9bff528 frag=0x7febb9bff4f8 size=48 used=1
              alloc'd from timer.c: new_sr_timer(150)
          start check=f0f0f0f0, end check= c0c0c0c0, abcdefed

This means that in function new_sr_timer, from file timer.c on line 150, 
somebody allocated a chunk of 48 bytes.

What you have to do now is to count how many similar allocations were 
made. If they are too many, that might be a memory leak. The "too many" 
order is strictly related to your scenario, so there's no magic way to 
find out just looking at the memory log. You have to investigate this by 
yourself, count how many allocations were made by different functions, 
and according to your scenario and traffic load decide whether that 
might be a memory leak or not.
