Error description
One or more Liberty servers abend with an ABENDSEC3 RSN=20000800 when when a Liberty server is forced down by a FORCE operator command, or using third party tooling. This condition occurs when a Liberty server is connected to an angel and where doing a FORCE (or worse) could cause the other Liberty servers which are connected to the same angel, to ABEND EC3 RSN 20000800. Liberty servers which are not connected to the same angel, or are connected to a different angel, are not affected. The angel must be running at the 19.0.0.3 or later level to have this problem.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Liberty for z/OS * **************************************************************** * PROBLEM DESCRIPTION: Using a z/OS FORCE command to terminate * * a Liberty server may cause other * * servers to terminate. * **************************************************************** * RECOMMENDATION: * **************************************************************** Using the z/OS FORCE command to terminate a Liberty server may cause other servers registered to the same Angel to terminate with an ABENDSEC3 RSN=20000800. There is code in an address space level resmgr to cleanup for a terminating Liberty server. There are paths through this code that are shared with the cleanup for an Angel. If an Angel process is terminated with registered servers then the servers will be failed with the ABEND EC3 and reason=20000800. The shared resmgr routine fails to check that the terminating process is an Angel process before terminating the set of Liberty servers registered to the Angel that the target Liberty server is registered with.
Problem conclusion
Code has been modified in the resmgr covering Liberty servers and Angel processes for address space termination to only terminate registered servers to the Angel if the Angel process is terminating. The fix for this APAR is currently targeted for inclusion in fix pack 19.0.0.10.
