Core file generated and finding it is dumped by kd4agent.(content of core file referring kd4agent)
==> I ran the core debugger command and got following result :
dbx /opt/itmtivoli/aix523/d4/bin/kd4agent /opt/itmtivoli/bin/core
Type ‘help’ for help.
warning: The core file is not a fullcore. Some info may not be available.
warning: The core file is truncated. **You may need to increase the ulimit
for file and coredump**, or free some space on the filesystem.
