[OpenSIPS-Users] tcp_blocking_connect for same ip but different listen port

[Bogdan-Andrei Iancu]

Hi Rahul,

What presence event is there ? Maybe the Notifies (first and second) are 
the result of the same event and triggered from the same process (this 
explaining the serial processing of them).

What OpenSIPS version are you using ? as normally, for sequential 
presence requests, the opening of new TCP conns is forbidden.
