Out of memory in UB 210: OOM killed process 12261 (kamailio) score 0 vm:1614768kB, rss:280200kB, swap:131408kB
Hi,
Our Kamailio server is crashing once per week, with following error:
Oct 1 06:25:06 kamailio kernel: [26982632.803789] Out of memory in UB 210: OOM killed process 12261 (kamailio) score 0 vm:1614768kB, rss:280200kB, swap:131408kB
Core dump was never created, probably it is because of my environment, but I will try to get it.
Server constantly eats memory, maybe some kind of memory leak?
Any help is highly appreciated!

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

Hi Daniel,
This modules what we are using:

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,
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

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!

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?

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.

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?

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

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?
With kind regards,

It may slow down a bit the processing, but may be the fastest way to catch the system memory leak.

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.

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!

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.

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?

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,
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?

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.

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, Daniel

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.

You are correct we are using heavily http_query.
I found following bug report:
https://bugs.centos.org/view.php?id=9391 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!

Hi Daniel,
I left valgrind running for little while, not sure if this will be enough.
Please find attached log file.

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.

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.

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.

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?

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
