Summary: [presence] crazy NOTIFY's
Just one client subscribed to itself (30004). All works well at the beginning, but after some time OpenSIPS starts sending *a lot* of NOTIFY's (no retransmissions) in the same seconds (for the same subscription dialog and with the same info).
This causes the client (Qutecom) replying "500 Retry Later".
I attach a very long capture, but go to line 3265 to see the issue.

I've attached a new file (sequential_crazy_NOTIFY's.txt). It's a SIP
capture of OpenSIPS sending 6 NOTIFY's in less than a second. All of these
NOTIFY's are part of the same subscription dialog, and are sequential
requests (from CSeq: 8 to CSeq:13).
Twinkle replies 200 for each NOTIFY, but other clients, as Qutecom, reply
"500 Retry Later" and the subscription gets lost.
