Problem summary
**************************************************************** * USERS AFFECTED: 01.All RDz users * **************************************************************** * PROBLEM DESCRIPTION: 01.RDz daemon raises an abend 0C4 in * * function tfree and JNI * * startProcess() * **************************************************************** * RECOMMENDATION: * **************************************************************** 01.In Rational Developer for System z - RDz - v9.1.1.2, the daemon process may raise an abend 0C4 in function tfree() called from Java_com_ibm_etools_zos_server_CoreJNI_startProcess()
Problem conclusion
01.Java_com_ibm_etools_zos_server_CoreJNI_startProcess() has a pointer whose value is not initialized in nomal cases. Only if a heap area is allocated only in some error conditions , the pointer is initialized to point the allocated area. Even if it is not initialized, Java_com_ibm_etools_zos_server_CoreJNI_startProcess() tries to free the pointed heap area and that could cause the abends in tfree(). RDz server code is updated to call tfree() only if the pointer points the allocated heap area.
Temporary fix
