[OpenSIPS-Users] Too many Hops error

I've configured two opensips to load balance incoming calls to freeswitch
servers.One of the two opensips works welle and routes calls to the
destination, but another causes the error "Too many hops".
I have the same configuration file for the two opsnisps.
Any help?
Here is the configuration file:
