#230 core files are not getting formed for opensaf processes running with user opensaf

[Mathi Naickan]

Opensaf is running with user opensaf. Now did a 'kill -6 <pid>' of one of the processes running with opensaf user. When tried the command on Node Directors, they restarted but no corefile is observed in /var/crash/opensaf. When other processes which are running with other users are killed, core file got generated. </pid>
