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:

Hello mailing list,
I've been working on setting up OpenSIPS on an EC2 instance, routing
traffic between nexmo and our gateway, a FS instance on a public IP. I
was kindly directed to an earlier thread on OpenSIPs and EC2
(http://lists.opensips.org/pipermail/users/2010-April/012393.html) but
have come to an issue I think is unrelated.
Here's the current architecture:
Nexmo -> EC2 NAT -> OpenSIPs -> EC2 NAT -> FS
I started with a walkthrough on the website
(http://www.unixnews.net/2010/09/dynamic-routing-with-opensips.html)
which roughly seems to be working. I've configured the gateway, the
routes, and so on. When I call my Nexmo number, it successfully routes
to FS and rings but, when answered, never connects, failing after 30
seconds. This is, as expected, the OK never reaching Nexmo and the RTP
negotiation never starting. I started poking around in wireshark and
ran into another issue: OpenSIPs is forwarding 9 invites in rapid
succession (less than a second) rather than just the one it received!
FS *seems* to handle this correctly (482 Request Merged) but it makes
the SIP trace an enormous mess and completely unreadable.
The opensips log is a mess, but isn't particularly useful:

Does anyone have any idea what would cause OpenSIPs to forward an
invite 9 times in less than a second? Fixing that should allow me to
move onto figuring out why it's not forwarding the 200 OK back to Nexmo.
Thanks!
