Messaging Server: No Core Dumps?

Seems as though this bit of preparation so that your system saves and notifies you about core files is often overlooked:
Core files are generated when a process or application terminates abnormally. Core files are managed with the coreadm command. To prepare for being able to collect core files, you need to use the coreadm command to configure a system so that all process core files are placed in a single system directory. This means it is easier to track problems by examining the core files in a specific directory whenever a Solaris OS process or daemon terminates abnormally.
Before configuring your system for core files, make sure that the /var file system has sufficient space. Once you configure Solaris OS to generate core files, from now on all processes that crash will write a core file to the /var/cores directory.
See 1.6 Configuring Solaris OS to Generate Core Files in Sun Gathering Debug Data for Sun Java System Messaging Server for more information on how to configure Solaris OS to generate core files.
