I'm very thanks for your quick response. Upgrading MINA version is next choice and I should find out problem in current using version and situation ^^
I'm wondering thread safety of all method because it isn't commented explicitly. Especially, I have a question about thread safety of NioSocketConnector.connect() method. I'v defined a global NioSocketConnector object and using in different thread because of reconnecting. Should I synchronized the connector?

Consider that : if you have sopme code in the codec or in your handler that is not thread safe, then you are going to have a problem. MINA is using threads to process sessions, so you may - and will - have many threads potentially sharing some informations. You have to make sure they are protected. You can store data into the session's attributes, so you are sure that two different sessions processed by two different threads won't compete for those informations. Now, there is one tricky part : you may have two threads processing one single session *of* you have added an Executor filter in your chain. In this case, you have to take care of the shared information for those specific sessions. Beside that, you should be safe.
