Description :Both the universe.log and IO dump logs show that a SIGNAL 11 was received but no core dump file can be located.
ulimit -Ha (and -a) show the coredump size as unlimited. The Node Settings -> Technical settings -> Maximum core size variable is set to the default, so a core file should have been generated with the default size.
Root Cause: N/A
OS: IBM AIX
Check where the core file should be saved to using the "lscore -d" command and check in the System error report (errpt -a) for possible causes. Set the variable (U_CORESIZE) to "0" for unlimitedto see if a core file will then be generated.
