Node crashed multiple times without any error

[ManuGowda]

Expected behavior

• Node should log errors before crashing for tracability
• Since the issue is unknow due to no log info, we need to fix the issue once identified

Actual behavior

Investigations currently suspended as the exact cause can be related to the application, pm2, or even external influence. If this happens again, further research is definitely needed to assure quality.
