Problem summary
**************************************************************** USERS AFFECTED: Users of MQ with SSL/TLS enabled channels Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A timing window existed whereby MQ did not correctly handle receiving the EAGAIN error code when reading data asynchronously from the socket. Within this window, this error code was treated as an unexpected error, which terminated the connection.
Problem conclusion
The MQ logic, used by both queue managers and native clients, to read data asynchronously from an SSL/TLS socket has been updated to correctly handle the EAGAIN error code in this scenrio. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.10 v9.0 LTS 9.0.0.4 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
