Hello Cao-

I don't know what might be going on. Is your disk full? Can you attach the default.etcd directory?

Thanks!

Brandon

Can you try just using a new data directory? I don't know what is wrong and I need you to tar and attach the directory if you want us to try and debug it.

SUSE 11 SP3 will ulimit virtual memory for users by default (see `ulimit -a`).

Please try:
```
ulimit -v unlimited
./etcd
```
