Hi there,
I have now approximately 400,000 routes defined in my LCR table and I would
like to make sure that I have enough memory allocated for it. I read
somewhere (a non official Kamailio site) about PKG_MEM_POOL_SIZE and
SHM_MEM_SIZE needing to be altered to handle the increased routes.
System is dedicated for the Kamailio 1.5.5 install and has 4GB of RAM.
Thoughts to what I need to change these values (or anything else) to
accommodate?
Thanks,
-graham

I set the shared memory to 512M via the command line at program start
and do not have any problems with my 500k routes.
Thank You

Hi Graham.
PKG_MEM_POOL_SIZE means fixed private memory allocated for each
kamailio process. You can edit config.h and set a higher value (i.e.
16 MB):
#define PKG_MEM_POOL_SIZE 16*1024*1024
About SHM_MEM_SIZE that's shared memory for all the processes. It
value can be modified with the -m paramenter when running kamailio
command:
kamailio -m 256
In case of LCR module with so many rules, indeed you need a high
shared memory value as rules are stored in shared memory.
And I also think that you need to increase private memory as well
since the database load task (gws and rules) is done using private
memory (hope I'm not wrong here).
Regards.

Thanks Stagg and Iñaki.
I already had the -m 512 in my init file, so it appears I am ok there.
I went ahead and recompiled with PKG_MEM_POOL_SIZE to 16MB and I'll see how
it goes.
Thanks again,

graham,
lcr module (at least the later versions) does not use any pkg memory.
it keeps all gws and rules in shm memory. you can check with kamctl
command how much shm memory you have left/used/etc.

Hello,
popping in to add some clarifications/hints regarding some statements in
this thread...
Loading of LCR rules from database is done through private memory, but
the records are loaded in chunks. So you should be fine with 4MB of
memory. If it is not enough for startup/reload time, just lower the
valuu of fetch_rows parameter (usually present in other modules that
load from database, as well).
http://kamailio.org/docs/modules/stable/modules/lcr.html#id2502056
Also note that private memory is sued temporary to load the rules, just
to transit from database to shared memory, then no private memory is
used for lcr records as Juha said.
Regarding the shared memory, looking at the source code will help to see
the overhead per lcr record and then just add the size of the data
loaded from memory (some such as domain names are variable size).
However, there is a simple way to estimate the need of shared memory by
loading for example 1000 records and then 2000 records. Using 'kamctl
fifo get_statistics all' you can see the used shared memory size in the
both cases, make the difference and then estimate the size per record.
As I said, that is practically to approximate average size per record.
If you reload the rules at runtime, you may need 2x shared memory size
for lcr rules - Juha can confirm that the module is (re-)loading rules
in a separate memory structure and then swaps with the active one, and
frees the old one afterwards, since I am not really using much this module.
Besides the lcr records, you need to have extra shared memory for
transaction processing.
Cheers,
Daniel

where are two shm tables (for gws and rules) per lcr instance and then
one extra of each that is used during reload.
