if used_size does not have variations, then it is no leak. The
variations of real_used_size is from fragmentation management --
each fragment has a structure associated to it.<br>

<div text="#000000" bgcolor="#FFFFFF"> Hello,<br>
<br>
the used size is pretty much the same after the reload, so
doesn't look as leak. If you do 2-3 reloads is
shmem:used_size staying around same value?<br>
<br>
It is clear boost in the fragments, I would say that after
start the number of fragments is quite low, because it
should contain the good records in memory as well.<br>
<br>
Btw, the version 3.3.x has options for defragmentation,
see the core cookbook, you can enable it.<br>
<br>

is this taken only after startup?
Get one at startup and another one
after reload, so it can be compared.<br>

I use MTREE to
load 5 million
rows from the

about 30 sec to
start kamailio and
it is running
great.<br>
Whern I check the
shmem usage I see
the data take
about 0.8G out of
4G i set on shmem.<br>
When i reload the
data while
kamailio is
running, the
memory usage rises
to 1.3G and stays
there (the second
and next reloads
stays on 1.3G as
well).<br>
Why doesn't it
return to 0.8G
after the reload
is completed?<br>

</div>
</div>
can you send the
statistics related to
shmem?<br>
<br>
kamctl fifo
get_statistics shmem:<br>
<br>
There are different
values there, some usage
come from overhead of
memory chunks
management.<br>
