thanks a lot.
so as i undestand, the real_used_size is the right value to calculate
size. but, it grows because of fragmentation data.
in the core, what does it mean "It is effective if MEM_JOIN_FREE
compile option is defined"
is there something else i need to do except adding to the cfg the
mem_join=1 ?
no, iirc MEM_JOIN_FREE is enabled by default -- this is an option to
turn the feature off at compile time. Let us know if the number of
fragments is lower.
Cheers,

Thanks,
The stuff i sent is from my test server that has 3.3.1 installed.
On my prod servers i use 3.2.x.
how would you explain that when kamailio starts (on prod with
similar data and same cfg) it take around 20% of the shmem, after
reload 30% and in time (6-8 weeks) it gets up to 39% ?
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.

I start with 4G of shmem.
It feels like a leak but i have trouble investigating it....
where would you look? The reload, the dialog or the avp's?

Hello,
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?
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.
Btw, the version 3.3.x has options for defragmentation, see
the core cookbook, you can enable it.

Hi,
here is the statistics after kamailio starts:
shmem:fragments = 28
shmem:free_size = 3800871312
shmem:max_used_size = 494132368
shmem:real_used_size = 494095984
shmem:total_size = 4294967296
shmem:used_size = 342642072
here it is after reload of the num table:
shmem:fragments = 9161531
shmem:free_size = 3654274496
shmem:max_used_size = 959885552
shmem:real_used_size = 640692800
shmem:total_size = 4294967296
shmem:used_size = 342654552
here is the cfg part for mtree:
#------- mtree params -------------
modparam("mtree", "db_url", CFGDB)
modparam("mtree", "mtree",
"name=odr;dbtable=service_odr_view;type=0;")
modparam("mtree", "mtree",
"name=oper;dbtable=service_oper_type;type=0;")
modparam("mtree", "mtree",
"name=permis;dbtable=service_permisions_to_oper;type=0;")
modparam("mtree", "mtree",
"name=num;dbtable=service_numbers_to_areas_view;type=0;")
modparam("mtree", "char_list", "0123456789")
modparam("mtree", "pv_value", "$avp(mtval)")
modparam("mtree", "pv_values", "$avp(mtvals)")
here is the number of raws from the DB:
SELECT count(*) FROM
`service`.`service_numbers_to_areas_view` = 4195528
and attached is the memory log.
thanks,
Uri

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

Hi,
I use MTREE to load 5 million rows from the
database. it takes about 30 sec to start
kamailio and it is running great.
Whern I check the shmem usage I see the data
take about 0.8G out of 4G i set on shmem.
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).
Why doesn't it return to 0.8G after the reload
is completed?
can you send the statistics related to shmem?
kamctl fifo get_statistics shmem:
There are different values there, some usage come
from overhead of memory chunks management.
Cheers,
Daniel
