Hi,

 

can you be a litle more specific of the steps of the install and where do i make the changes?

in the source tree, edit the file Makefile.defs and set:

MEMDBG=1

then run:

make all
make install

some words of what is the diff between f_malloc and q_malloc will be great :-).

q_malloc is more debugging purposes, keeping more information for each chunk, therefore the overhead is a bit higher than with f_malloc, but because keeps more details, it is faster to find the fragments that can be joined.

thanks,

Hello,

ok, I will look over it. At this moment the f_malloc (which is enabled for 3.3) has a pretty inefficient mem join implementation, can you try with q_malloc? Edit Makefile.defs and set:

MEMDBG=1

Then compile and install.

The join operation should be faster, let's see if you get blocking issues with this one.

Daniel

Daniel hi,

 

I attached 2 txt files.

One with mem_join=1, the other with mem_join=0, and the info you asked for.

Let me know if it is OK.

 

Thanks,

Uri

Hello,

if you set memjoin to 0, do you see any difference?

Can you try again (with memjoin 1 as well as 0) and send the output of:

kamctl mi get_statistics shmem:

before executing the reload commands?

When it gets to 100%, can you see which process is using the cpu and attach to it with:

gdb /path/to/kamailio PID

then do:

bt full

and send output here?

Cheers,
Daniel

After some testing I notice the following:

First reload of 5 million records after kamailio started took about 9 sec.

Second reload (4 minutes after the first one) took 60 sec.

The third one (again about 4 minutes after the secind) got kamailio to use 100% cpu and after 13 minutes! i killed it.....

 

I can understand that the memory manger works harder, still, any ideas on how to use mem_join and keep on reloading data.

(in real life our data loads 5 million records once a day when almost no traffic. still after a few days it stops...)

 

Thanks,

Uri

Hi,

I am using MTREE and DIALPLAN modules to load lots of info to kamailio. (6 million rows).

When kamailio was running with 3.2.1 (no mem_join=1 option), the used size was increasing but the process of loading the data was fast eanough.

I upgraded to 3.3.2 and set mem_join=1. Now the loading process take about 10 time longer and sometimes stops kamailio from responding to traffic.

Any ideas?

Thanks,

Uri
