2. There could be multiple error in the alert log file:

ORA-00600: internal error code, arguments: [4400], [560], [], [], [], [], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [729], [33608], [space leak], [], [], [], [], [], [], [], [], []
ORA-00020: maximum number of processes (2000) exceeded
ORA-20 errors will not be written to the alert log forthe next minute. Please look at trace files to see all the ORA-20 errors.
       Process m000 submission failed with error = 20
ORA-00600: internal error code, arguments: [kghfrmrg:nxt], [0x7000102224A7630], [], [], [], [], [], [], [], [], [], []
ORA-07445: exception encountered: core dump [kghfre()+224] [SIGSEGV] [ADDR:0x7C7242A64844E8A6] [PC:0x1000BB640] [Address not mapped to object] []
ORA-00602: internal programming exception

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

... kghfrmrg <- kghfre <- kghssgfr <- ksmsgfr <- kksParentHandleFreeCbk <- kglhdda <- kglhdd ....
