[mpls-linux-general] zebra crashes when receiving label mappings

[Nuno L. <nun...@gm...>]

Hi guys,



I have installed mpls Linux on kernel with the RPM packages for fc10, and
I’m using the ldp portable on quagga for mpls signaling.



The problem I’m having is related with ldpd and zebra deamon on quagga. LDP
sessions are established with success, but when it receives label mappings
the zebra deamon crashes (see logs below).

Ldpd deamon doesn’t crash but I can see a broken pipe happening. I believe
this is caused by zebra crash.



Does anyone can help me?



Thanks and regards,

Nuno
