[OpenSIPS-Users] async- issues- 2.2.2

[Ramachandran, Agalya (Contractor)]

Hi,

Another information may help you to find this issue.

Am changing the "req_body" in the rest_methods.c, as per the REST API server is expecting the payload value.
If I change this "req_body" in REST_POST as well, and if the Call-Id length is > 56, it crashes in the POST call too.

Regards,
Agalya

Hi Liviu/team,

When I try to do an asynchronous REST_PUT call in OpenSIPS 2.2.2, I see the below observance and issues.
All the calls are made from sipp client.

No

Test Scenario

Result/observation

1.

Call-Id length < 50

Works perfectly fine

2

Call-Id length  >54 and < 56

No crash observed. But error in curl_multiperform

3.

Call-Id length  > 56

Opensips crashes at liburl.


Please find the details for test 2 and test 3.
I have tested with REST_POST with case 3, I didn't observe any crashes.
Please let me know what could cause this issue and how can I fix this?

Test2:
