![]() APAR status Closed as program error. Error description During BBOASRx(CR) termination, CEEDUMP was produced for SIGSEGV in BOSS_Address_Space::write_bascb_field(fields,void*). It seems to be bbo3bas failed to access to BACB.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: SIGSEGV for ABEND0C4/ABENDS0C4 in * * RasLock::releaselocknocheck in * * bborlock.cpp after ABEND0D6/ABENDS0D6 * * from BBO3SETS called from * * BOSS_Address_Space::write_bascb_field * * during server region termination. * **************************************************************** * RECOMMENDATION: * **************************************************************** During server region termination, after freeing the trace object, the server may take an 0D6 abend trying to clear the pointer to the BTRC because the CTL region PC routine required to clear the pointer is gone because the CTL region terminated prior to the server region. The first processing the signal handler for the 0D6 is to attempt to unlock the mutex which protects the trace processing. However, this object has been freed (and the pointer not cleared, as above). The attempt to release the mutex results in an ABEND0C4. This results in another signal for which the signal handler fails the same way, in a loop until something stops it (not clear what that was).Problem conclusion Support was added to bborexit.cpp to conditionally proceed with the trace unlocking process during signal handler execution based on whether trace objects can be found. APAR PQ52124 is associated with SERVICE LEVEL W400035 of WebSphere Application Server V4.0 for z/OS and OS/390.Temporary fix Comments
