[OpenSIPS-Users] EC2 and rapidly repeated invites

[Bogdan-Andrei Iancu]

Hi Kurtis,

On a first look, it seems your script doing doing a kind of looping 
(maybe a recursive call of a route or so) - at least this is what the 
log errors tell.

You can try the script_trace() function to understand how your script is 
executed:
