Problem summary
**************************************************************** USERS AFFECTED: All users of IBM App Connect Enterprise V11. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Intermittent abends of integration servers and integration node agent processes due to an EXCEPTION_ACCESS_VIOLATION may be seen, particularly on the Windows platform.
