Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty for z/OS * **************************************************************** * PROBLEM DESCRIPTION: Storage shortage in below the bar * * private storage when using Liberty * * inside a CICS region. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a Liberty server connects to the angel process, and is recycled inside a CICS region, approximately 10 megabytes of below the bar storage is leaked when the Liberty server is recycled. This leak repeats each time the Liberty server is recycled. Eventually, there will be a storage shortage below the line, and the JVM will not be able to allocate enough memory to initialize. The storage that is leaked is in subpool 249, key 2.
Problem conclusion
Code was added to free storage used by Liberty in subpool 249 when the Liberty server is recycled. The fix for this APAR is currently targeted for inclusion in fix pack 18.0.0.4.
