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.
Cheers,
Daniel
