![]() APAR status Closed as program error. Error description Intermittently, Websphere for zOS Servant region encounters various abends ( S0C4, SA78, S283-4C ) and the produced symptom dumps all point into RACF module IRRIA00. These abends may show up when garbage collection cycle is started. . The failing TCB may have the following stack trace: RUNAS::freeCredential(long) Java_com_ibm_ws_security_core_EJBRunAs_freeCredential com/ibm/ws/security/core/EJBRunAs.freeCredential(I)I com/ibm/ws/security/auth/PlatformCredential.finalize()V . This is due to the first time an ACEE is to be deleted in the PlatformCredential finalization path. APAR PK04957 modified the way the ACEE`s are removed. This causes a leak with the ACEE`s. This problem can occur with security enabled for a run where garbage collection happens for the PlatformCredential. . The Servant Region may issue RACF abend283-04C. The SR may continue to run but to get rid of these abends, one may have to restart the SR. This should clear up the RACF abends. . This apar only affects customers who have global security enabled and also use sync to thread functionality. This apar is a fix for PK14144. .
