memory leak? a problem about DownstreamMessageEvent

[chris]

the problem about decoder i had resolved at last week , i found the core
problem was i config the decoder and handler as singleton,now it were not
singleton,  but the memory leak still exist.
i upload the jmap dump file at http://121.101.216.141:8080/0104dump

and i startup the jhat service at http://121.101.216.141:11411

if you can not access http://121.101.216.141:11411  please just wait for a
moment ,because the 0104dump size=2.7G, i'm startup jhat at  13:10

i'm waiting for your reply online.
