This is a question on forum (in Chinese):
http://gceclub.sun.com.cn/NASApp/sme/jive/thread.jsp?forum=22&thread=43920
The user is using glassfish_v2_b36, configured 4 virtual servers in
domain1, each virtual server corresponding to a domain name. This works
fine. But after some time, the server stops responding to requests from
web pages, as if the server is dead. After a few hours, everything is
back to normal. Any ideas?
