[OpenSIPS-Users] The cause of 'max nr of branches exceeded'

[Bogdan-Andrei Iancu]

Hi Eran,

The error you get means you reached the maximum number of branches per 
transactions. Branches are created during parallel or serial forking and 
there are max 12 configured in OpenSIPS.

So, check your script, maybe you have a run-away forking creating more 
than 12 branches.
