[mpls-linux-devel] ldpd crash and could not start again
|
From: 刘磊 <orp...@ms...> - 2008-05-07 10:14:18

Hi all.
Thank you for help.
I patch the quagga-mpls.diff to quagga-0.99.6 and configure && make it.
BUT I found that when I telnet to the shell of zebra, ldpd will crash and can not start again.
If I start ldpd and ospfd, telnet any are ok.
But I start zebra after above two, and telnet to 2601(zebra's shell port), ldpd crashed.
The strace of start ldpd again is follow:
