Hi,
From the syslog when kamailio start ups I get the following:

Yes, these show empty htable slots.
Do you have any idea on why htable module does not load the data in
the memory ?
Needs some troubleshooting as looks not to work from a certain amount of
data.

Hi,
I don't see where the mysql is stacking but if I read correctly
in http://kamailio.org/docs/modules/1.5.x/htable.html
_/The number of entries in the table is 2^size/_ : 2^14=16384
rows data and i have 2.000.000 rows so maybe it is not possible
to load them..But you know better of course.
no, that is the number of
slots (buckets) in the hash table, not
the number of items that can be loaded -- some more technical
aspects of hash tables:
http://en.wikipedia.org/wiki/Hash_table
The number of items in htable is only a matter of shared memory.
The number of slots controls access speed -- higher number gives
less collisions.
You said at a moment that you could start, but htable was
returning only null: put a sht_print() in config to see the
content of the htable (you probably need high debug level:
debug=5) with the first sip request.
Cheers,
Daniel

Hi,
The error I get is the following:

I'm running kamailio with 8M private memory per process
and 2048M shared memory.
When kamailio is getting the data from mysql is passing
it all the data chunk in private memory and then in the
shared memory?
It is loaded in chunks of rows -- you can tune it with a
module parameter:
http://kamailio.org/docs/modules/3.0.x/modules_k/htable.html#id2529075
Try to play with it to see if you get better results. You do
not need more private memory, 8MB is ok.
Maybe the mysql server is closing due to lot of loaded data.
Have you got any figure what is the number of rows when it
starts losing the connection?
Cheers,
Daniel
because if this is the case then I need more than 1000M
in private memory.
Cheers
Alex
P.S. i don't get any errors from mysql.
