Description of problem:
When I tried to copy vmcore from netdump-server to netdump-client, I encountered a weird problem:
[root@pogolinux-2 ~]# ls -lsh /var/crash/10.16.65.30-2010-12-14-22\:09/
total 29G
76K -rw-------  1 netdump netdump  67K Dec 14 22:55 log
16G -rw-------  1 netdump netdump 260G Dec 14 22:55 vmcore
The vmcore takes 16G, but scp tried to copy 260G. In our network condition, it'll take more than 30hours!!!
