Re: [SR-Users] Auth_xkeys module - freeing already freed pointer

Hello,

can you try with master branch or with the patch from the next commit?

- https://github.com/kamailio/kamailio/commit/01f5ecbc45c236daea62d6638a02c168...

If all is ok, I will backport.

Cheers, Daniel

Hello Henning,

The function that seems to be causing this is "auth_xkeys_add".

Let me know if do you need something else.

Thank you for the support José

Hello Jose,

this is not a normal error, it shows a redundant (double) free
which is
detected from the internal Kamailio memory manager. This should be
fixed.

Can you investigate at which function call from the auth_xkeys
module in the
kamailio cfg this error is printed?

Best regards,

Henning
