We have around java virtual machines with limited memory, and MongoDB. Deployed processes are randomly getting killed/terminated abruptly in time. No matter java process, nodejs or mongodb process. We tried OOM configuration changes also which did not help us. We found no log or trace for killed processes. Thought it is a memory issue but we have enough memory.

System and Deployment Specs :

OS : RedHat
RAM Memory : 32 GB
HDD : 120 GB
Applications Deployed : around 10 jetty application services, mongoDB, Nodejs, Apache web server

Tried in local machine with few memory loaders also, didn't work and could not be able to reproduce.

We are running out of clues...

Have you see OOM-killer logs in `dmesg` output? – Alexander Tolkachev Jul 27 '17 at 08:16

If it's physical machine, run a memtest, sounds like bad RAM to me (considering you don't see OOM Killer logs in /var/log/messages). – Florin Asăvoaie Jul 27 '17 at 08:17
ya Alex. But none were there. – user135968 Jul 27 '17 at 08:18
we checked all possible logs, did not get a clue. We tried to simulate in local we failed. – user135968 Jul 27 '17 at 08:19
Reboot the machine with a CentOS install / rescue disk and run memtest from the Grub menu of the disk. – Florin Asăvoaie Jul 27 '17 at 08:46
