[OpenSIPS-Users] Possible MYQL B2B problem?

[Lee Archer]

Hi Ovidiu, could I not use a database for this and each server would do it locally?

Regards

Lee

Thanks for the explanation.  So does this problem cause any calls to drop?  I haven't restarted the server or made any changes to the b2b tables so don't quite understand how this could have happened.

There is an issue with the b2b_logic module.
If a b2b_logic context is saved in the db and the b2b_entities corresponding to the b2b_logic contexts are lost, the db is not properly cleaned up.
When a new call comes in, a b2b_logic context is created and it may have the same key as the saved old b2b_logic context in the db.
When a db operation is performed on that call (like inserting a new b2b_logic context with the same id as the one in the db) the operation fails and you see those errors.

It might be possible that you arrived in this scenario after an opensips crash that left the db out of synch.
When opensips was restarted, the b2b_logic context failed to load but it was not cleaned up in the db.

In your case, you should see that you have in b2b_logic table a context with si_key='414.0'.
You will need to manually delete that one from the db.

When opensips starts, there are ERROR logs for this kind of situation:
ERROR:b2b_entities:b2b_restore_logic_info: No dialog found for key [bk2bk.287.95]
WARNING:b2b_logic:b2bl_add_tuple: Failed to restore logic info for tuple:entity [644.0][0]
ERROR:b2b_entities:b2b_restore_logic_info: No dialog found for key [bk2bk.132.8088290]
WARNING:b2b_logic:b2bl_add_tuple: Failed to restore logic info for tuple:entity [644.0][1]

In this case, the b2b_logic context should be removed from the db because the restoration failed.


Please open a bug report about this.
