Re: [mpls-linux-general] LDP :(

in fact, in searching, I think the probleme is somewhere else...
I fand this error message :
Program received signal SIGTERM, Terminated.
malloc_consolidate (av=0xb7f5e480) at malloc.c:4400
4400 malloc.c: No such file or directory.
in malloc.c
and, I have a malloc.c file but it is located in filesystem jff2...
and the line number told by gdb don't correspond at all... these numbers are
greater than the total lines in the file....
ideas ???
thanks
