[Daniel-Constantin Mierla]

I think this issue was exposed only on centos/redhad packages, which is
harder to detect as we set the OS type to linux. If someone comes up
with a solution, I am ok, otherwise I think it's fine to add some
remarks in the docs.

Cheers,
Daniel

Hello,

you don't have to generate the readme files anymore, they are generated
automatically on the server after committing the xml files.

For creating the pull requests, just search the web/github about how to
do it for github -- there are some good manuals in place hosted by
github.com, but I don't have the links at hand right now.

Cheers,
Daniel

[Olle E. Johansson]

I think we need to update the Make system instead of the docs to avoid this 
version.
Or implement some code like we have for OpenSSL that outputs warnings at 
runtime.

[Jurijs Ivolga]

Hi Daniel,

I found modules what are impacted by this leak:

http_client
utils
xcap
http_async_client
auth_identity
xcap_client

I would like to update documentations, but this is first time when I'm
updating documentation.

I believe I need to update xml file for module. Should I then regenerate
readme file as stated here:

https://www.kamailio.org/wiki/devel/how-to/module-readme

Or not?

Then I believe to create pull request with my changes. Correct?

Maybe you have manual for this?

With kind regards,

Jurijs

 Hello,

 that's the way it was done for older versions of kamailio.

 In master and 4.4 the memory debugging is turned on and it is reflected
 by the presence of DBG_SR_MEMORY in the output of 'kamailio -v'.

 Anyhow, what you reported is not a leak inside kamailio memory manager,
 but a leak of using system memory, so it is not affected by DBG_SR_MEMORY
 and cannot be troubleshooted using the mechanisms for pkg and shm managers.

 Cheers,
 Daniel

200MB in 8 days it's still relevant and a leak. Maybe you can run again
with valgrind...

Unless it is unclaimed memory by kernel:

Hi Daniel,

After 8 days there is still small memory leak, 200MB of Ram wasn't freed
during this 8 days, please check diagram below.

1) Is this something usual?
2) Memory leak seems very small, maybe I should never worry about this?
What you think?

Thank
you!

 Hello,

 from the logs, it seems to be related to curl library, I see many
 reports like:

 That's like almost 200KB lost in this report.

 From the list of the modules, I see you have utils and I guess you use
 http query function from there, is it?

 Cheers,
 Daniel

Hello,

thanks -- coming in my mind now, xcap_client should use also the curl
library.

Cheers,

Hi Daniel,

I will test couple more days and later I will try to add some comments to
utils, http_client & HTTP_ASYNC_CLIENT(not sure if there any other modules
which use curl, but I will check) modules when I will be 200% sure that
issue is gone.

With kind regards,

Jurijs

 Hello,

 that's the way it was done for older versions of kamailio.

 In master and 4.4 the memory debugging is turned on and it is reflected
 by the presence of DBG_SR_MEMORY in the output of 'kamailio -v'.

 Anyhow, what you reported is not a leak inside kamailio memory manager,
 but a leak of using system memory, so it is not affected by DBG_SR_MEMORY
 and cannot be troubleshooted using the mechanisms for pkg and shm managers.

 Cheers,
 Daniel

Hello,

ok, so that was...

Maybe it would be good to add a note to the docs of the module about
this issue so people become aware of it. I guess the other http_*
modules are affected. Pull requests or other suggestions are welcome, of
course!

Cheers,

Hi Daniel,

Thank you a lot, it looks that issue is solved, after updating libcurl.

I was using following manual for updating libcurl, in case if somebody will
have same issue.

Hi Daniel,

You are correct we are using heavily http_query.

I found following bug report:

https://bugs.centos.org/view.php?id=9391

I will try to update to libcurl 7.44 and check if this help.

Thank you a lot Daniel!

[Daniel-Constantin Mierla]

Hello,

that's the way it was done for older versions of kamailio.

In master and 4.4 the memory debugging is turned on and it is reflected
by the presence of DBG_SR_MEMORY in the output of 'kamailio -v'.

Anyhow, what you reported is not a leak inside kamailio memory manager,
but a leak of using system memory, so it is not affected by
DBG_SR_MEMORY and cannot be troubleshooted using the mechanisms for pkg
and shm managers.

Cheers,
Daniel

 All json operation is pretty much same, we are using

 In attachment you can see memory consumption. On the

 which don't face internet. As you can see memory
 consumption is pretty dramatic.

 Thank you for your help!

Hi Daniel,

I tried to compile with memory manager in debugging mode like this:

MEMDBG=1 make cfg 'include_modules= textopsx db_mysql jansson json
snmpstats tls utils uuid'
make all
/etc/init.d/kamailioa stop
make install
/etc/init.d/kamailioa start

But still I'm getting nothing on:

kamailio -I | grep DBG_QM_MALLOC

Any hints?

[Daniel-Constantin Mierla]

Hello,

There are some results when searching for memory leak on openssl 1.0.1,
but might not be valid for this case.

Would you be able to run kamailio through valgrind? It may slow down a
bit the processing, but may be the fastest way to catch the system
memory leak. Maybe you have an instance will less traffic and you can
run through valgrind for a while, you don't have to wait until you get
the OOM.

Cheers,
Daniel

 Hello,

 it looks like a leak from the system memory, not from kamailio's pkg or
 shm memory. This can be due to an improper use of an external library
 (e.g., libxml2) by a kamailio module or because of a problem in the 
 library.

 Can you list the modules used in your config (the loadmodule lines)? I
 will try to guess from the list which one relying on external libs with
 higher risk of leak issues.

 Also, provide the version of kamailio you are using (kamailio -v).

 Cheers,
 Daniel

Hello,

the tls module in kamailio is using shm memory, but can be something
internal for libssl. What operating system do you use and what is the
libssl version?

Cheers,
Daniel

Hi Daniel,

I do not use puke.top rpc command. Maybe this issue related to TLS? Servers
what has this problem are utilizing TLS heavily, servers which do not has
this problem use UDP.

With kind regards,

Hello,

are you using pike.top rpc command? I noticed in the code that it uses
system malloc, but I haven't investigated further yet, first to see if
this would be a possibility ...

Hi Daniel,

We do not do any external operations.

We are using janson 2.7 everywhere. I will try to update to latest janson
version tomorrow.
All json operation is pretty much same, we are using only jansson_get.

In attachment you can see memory consumption. On the right 2 servers which
are faced internet on the left which don't face internet. As you can see
memory consumption is pretty dramatic.

Thank you for your help!

With kind regards,

Jurijs

Hello,

are you doing different external operations than on the other instances,
like mi/rpc commands.

>From the list of the modules you exposed, I think jansson has the higher
probability to work with system memory. Are you doing different json
operations in config that in the other instances of kamailio? Are you
using same version of libjansson everywhere?

Cheers,
Daniel

[Jurijs Ivolga]

Hi Daniel,

This modules what we are using:

loadmodule "mi_fifo.so"
loadmodule "kex.so"
loadmodule "corex.so"
loadmodule "tm.so"
loadmodule "tmx.so"
loadmodule "sl.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "maxfwd.so"
loadmodule "textops.so"
loadmodule "siputils.so"
loadmodule "xlog.so"
loadmodule "sanity.so"
loadmodule "ctl.so"
loadmodule "cfg_rpc.so"
loadmodule "mi_rpc.so"
loadmodule "dispatcher.so"
loadmodule "utils.so"
loadmodule "path.so"
loadmodule "ipops.so"
loadmodule "jansson.so"
loadmodule "auth.so"
loadmodule "nathelper.so"
loadmodule "tls.so"
loadmodule "htable.so"
loadmodule "pike.so"

We have several other Kamailio instances but they are not faced to internet
and they do not have such memory issue. That other Kamailio instances have
same modules,  except modules listed below. So if you think that issue is
inside external library, probably we need to check first modules from list
below.

loadmodule "ipops.so"
loadmodule "auth.so"
loadmodule "nathelper.so"
loadmodule "pike.so"

But maybe this other Kamailio instances do not have this memory issue, just
because they did not face to internet and did not have same load as
instances with memory issue.

Hello,

it looks like a leak from the system memory, not from kamailio's pkg or
shm memory. This can be due to an improper use of an external library
(e.g., libxml2) by a kamailio module or because of a problem in the library.

Can you list the modules used in your config (the loadmodule lines)? I
will try to guess from the list which one relying on external libs with
higher risk of leak issues.

Also, provide the version of kamailio you are using (kamailio -v).

Cheers,
Daniel
