Memory fault(coredump)

This issue can occur on any Siebel Env, servers hosting on Linux. The issue can occur in an existing running env or on an upgraded env.

After starting the server, we can see the start_server command is successful but the services did not start properly.

[parthod@server1 siebsrvr]$ list_server all
Siebel Server "server1" (Enterprise "PROD_ENT")
started at Sat May 28 10:57:34 2016, pid: 8409 (Service process is not running), autostart: no

Even after stopping the server and starting it again will give error something like below --
[parthod@server1 siebsrvr]$ start_server all

Cleaning up previous execution of PROD_ENT::server1 ...

/server1/siebsrvr/bin/reset_server: line 119: 9978: Memory fault(coredump)

Even doing a clean startup(see this link), is not helping and the services are not starting properly. This issue occurs when core services are not starting properly. Even stopping the core services and starting the server will not help.

Solution -- Delete the core services directory from the server and then start the server. Core services directory is located under /server1/siebsrvr/mw/.mw/core_data
In my case, I removed the directory name server1 which was present under core_data
