Hi, Yuehua,

This is not an answer to your question, but I think if you have no special
reason to use espresso 3.2.3, you'd better upgrade to 4.0.4 and try again.

Since we are on the same campus and I guess you're using our Altix 4700,
if this is true and you're willing to, you can run the command below to get
the latest compiled copy from my home:

scp -r hqzhou at 210.119.46.90:/disk3/hqzhou/espresso-4.0.4 /your/home

Call me at 83686750, I'll let you know my password.
