Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty Profile - Websockets * **************************************************************** * PROBLEM DESCRIPTION: Connection leak, therefore a memory * * leak, may occur if the server reads * * Websocket Close frames in fragments. * **************************************************************** * RECOMMENDATION: * **************************************************************** In rare cases a close frame coming from a client may be split across more than one TCP/IP data read on the server. This can result in the websocket connection objects not being discarded at the server, and therefore slowly building up over time.
Problem conclusion
Websocket code was change to properly deal with close frames that are split across more than one "read" of the TCP/IP data that is on the network. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.9 Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
