[OpenSIPS-Users] opensips crashes in 2.2.2

[Ramachandran, Agalya (Contractor)]

Hi Liviu,

I have tested by applying your patch. Crash for scenario 2 and 4 is not  happening now. Thank you for the fix.
As well scenario 5 still exists only in case if I give URL as https. With http URL it is working fine, no crash observed.

One more observation for scenario 2 and 4 is as follows:

Once I saw there are several core dump files, being created at the same time when doing load test with rest_put().
Even though core dump is created opensips process is running. As well if I see the core dump trace, it says couldn't access memory.

I will repeat the test couple of more times, when I find time and if the issue happens again will report you.

Regards,
Agalya

Hi Agalya!

I have pushed a fix for crashes 2) and 4) on all branches [1]. If you are able to test it out, could you please also re-do test 5), and see if the problem is still there? Many thanks for all the help!

Hi team,

Missed to mention about one information in the previous email .
In Scenario 5, with REST API as asynchronous, it crashes only when am using https://url.
No crash is observed in asynchronous, when it is http://url.

Agalya

Subject: opensips crashes in 2.2.2

Hi team,

I was trying to a load test in OpenSIPS 2.2.2  version. Below are the few scenario's I have tested and their observance as follows.
We have two REST Server, out of which I find different behavior when I use REST API asynchronously - Scenario 3 and Scenario 5.

Am testing on a Vitual machine with 8 core CPU and 20 GB RAM.
Below are the configurations made:


*         Children = 24 (opensips.cfg)

*         Cps = 100 (sipp)

*         S_MEMORY = 1024 (/etc/default/opensips)

*         P_MEMORY = 64 (/etc/default/opensips)


No

Scenario - Script used

Result observed

Time when crash occurred

1

Default script

No crash observed



2

REST API service used with rest_put() - synchronous - Rest Server 1

Crash occurs when load testing. Single call works fine

Randomly at any point when it crosses more than 1000 calls

3

REST API service used with rest_put() - asynchronous - Rest Server 1

No crash observed



4

REST API service used with rest_put() - synchronous - Rest Server 2

Crash occurs when load testing. Single call works fine

Randomly at any point when it crosses more than 1000 calls

5

REST API service used with rest_put() - asynchronous -Rest Server 2

Crash occurs for even single call.

When processing the response received.


Am attaching the crash dump with this email. First two dumps are when rest api is used synchronously
3rd dump is when rest api is used asynchronously, when processing response.

Please let me know if any more information is needed.


Regards,
Agalya
