Processes that have run PLSQL blocks may fail at session cleanup with:

ORA-07445: exception encountered: core dump [plcurClose()+24] [SIGBUS] [ADDR:0xDF] [PC:0x108C070F8] [Invalid address alignment] []

From the trace, it can be identified if the process was deleted and that the error was reported at cleanup by seeing the DEL flag:

flags: (0x8000041) USR/- flags_idl: (0x21) BSY/-/-/DEL/-/-

Review of the generated tracefiles reveals a call stack similar to:

plcurClose <- kgscReleaseACursor <- kgscReleaseCursorGroup <- kgiscl <- ksuxds <- ksudel <- kkjsexe <- kkjrdp
