Error description
The WebSphere Application Server for z/OS "roadkill" feature that attempts to free up threads that appear to be hung has a signal handler that gets control for SIGVTALRM. This signal handler, RasSignalHandler2, invokes ISGENQ to release an ENQ and in some cases the ENQ may already have been freed, leading to the system abend 0430 with reason code 02390815. This originally surfaced to the user as an abend and dump due to USER COMPLETION CODE=4091 REASON CODE=00000006 The logdata revealed the underlying issue to be SYSTEM ABEND CODE: 0430 ABEND REASON CODE: 02390815
