PROBLEM TO BE SOLVED: To provide a system and a method for an automatic session resources cleanup that occurs due to a client/server session that a client has requested use of server resources during the session. SOLUTION: During each session, a list of resources allocated to the session and associated wit a client is maintained, and when the session terminates naturally or unnaturally, the allocated resource are released, and, by the different session with same client or any of different clients, the same resources can be used thereafter. If, for some reason, the connection between the client and the server is broken down, or if the program is terminated abnormally or the like, terminating unnaturally, usually, there is not other way for making the server release the resources than to make the client send a parting message to the server. This invention determines the time when the session is terminated to release the resources relevant to the client.
