Hello,
I am emulating a network with MPLS and LDP using Netkit (based on UML).
However, whenever I try events such as link/node down using commands like
"ifconfig ethx down", I always notice that the zebra process crashes on some
of the machines. The log looks like the following:
ZEBRA: Received signal 11 at 1182778885 (si_addr 0xe, PC 0x80539cf);
aborting...
Program counter: /usr/sbin/zebra[0x80539cf]
Backtrace for 9 stack frames:
/usr/lib/quagga/libzebra.so.0(zlog_backtrace_sigsafe+0x47)[0x400532b7]
/usr/lib/quagga/libzebra.so.0(zlog_signal+0x216)[0x40053866]

/lib/libc.so.6(__libc_start_main+0xdc)[0x402d9ebc]
/usr/sbin/zebra[0x8050721]
BTW, I have used the mpls-linux 1.955 patch when building a new kernel. And
I have used the quagga rpm package for fedora5 from this site and converted
it to a .deb during my installation.
Could anyone please help me with the problem? Thanks.
