z/OS Agent processing File Transfers crash with U02000102 and U02000143 errors
Article ID: 85045
CA Automic Workload Automation - Automation Engine
Error Message : U02000143 General GSS error: 'gss_acquire_cred() rc=458752(1004)'. “U02000102 Error when calling the function 'getpwnam', error code '157(EDC5157I An internal error has occurred.)'.” (After canceling the filetransfer)
When performing a File Transfer on a z/OS Agent the agent crashes and the JOBF is stuck with a KEYSTORE error similar to this:
Can't open //'HLQ.LIB.KEYSTORE'
While other File Transfers on the same Agent and Host process without error.
Cause type: Defect Root Cause: File transfer fails in the initiation phase, while accessing the keystore dataset. As more transfers run on the same agent, a user switch may occur in a running transfer thread, right before the main agent thread tries to access the keystore.

Update to a fix version listed below or a newer version if available.
Fix Status: Released
Fix Version(s): Component(s): Agent MVS
Automation Engine 12.1.0 - Available Automation Engine 12.0.2 - Available Automation Engine 11.2.5 - Available
Workaround : Use File Transfer (FT) option FT_THREAD_LEVEL_SECURITY=YES to allow each transfer to run under the FT login user context
This will prevent concurrent effective user switches in the Agent process.
