Why daemon application is not generating coredump on crash?

Issue

• We have our own application which starts as daemon, it is not generating coredump upon crash.
• We have an in house developed C++ application that is running on Prod servers. 2 days back application got crashed with segfault error on a server. Today it got crashed on different server with exact segfault.

Jan 27 09:13:12  kernel: app_name[10918]: segfault at d1f0 ip 00000037c813382f sp 00007f221ae88a78 error 4 in libc-2.12.so[37c8000000+18a000]
Jan 27 09:13:12  init: app_name process (10683) killed by SEGV signal
Jan 27 09:13:12  init: app_name process ended, respawning

• No Luck even after changing OpenGPGCheck = no
