Description :After IO crash, no core was created, whereas core creation is allowed on the system.
Environment
OS: All Linux/Unix OS Version: any
Cause
Cause type: Configuration Root Cause: IO was launched with a user with ulimit -c value set to "0" preventing Dollar Universe to create a core file in case of a crash.
Resolution
Be sure to have set a value for ulimit -c / ulimit -Hc not equal to 0 so that applications can create a core dump in case they crash.
You can set this to "unlimited" to be sure core dump will be complete.
Modify the value in ulimit -c and ulimit -Hc setting core file size with the value 'unlimited'
In case the system is AIX, fullcore generation should also be enabled, in order to do so, consult the following IBM documentation: http://www-01.ibm.com/support/docview.wss?uid=isg3T1011816
