Hi,

I wonder about the difference between “used” and “real used” shared memory in Kamailio.

Each allocated chunk of memory is encapsulated in a fragment that has additional fields (e.g., to be able to find prev/next fragment). Also, the allocator rounds up the size to match the internal bus size, otherwise can get a SIGBUS on various architectures (e.g., xmalloc(3) will return a chunk of size 4 on 32bit system).

The used is counte only from parameters of xmalloc. All the extra fields and padding the size are counted to get the real used.
