Good day.
I configured Eduroam Federation level server and 2 Institutionals.
Everything works fine before I added the second Federation level server.
The first problem is, that Institutional servers can not fail over the
request on the second Federation level server if the first one is dead. it
dosen't even reject the request normally and just give this error *"Internal
sanity check failed in event handler for request 0: Discarding the
request!"*
After this I tried to comment out all the configuration I had made in
proxy.conf for the second FRL, but it gives the same error again if its
Home server (first FRL) is dead.
Sometimes I get this error even if all servers are alive.
I really don't understand now what is the matter.
Can anyone help me please ??
Here is the debug of institutional server, which gives the error:
