Java process suddenly stops on Linux Hyper-V VM

Question

I am running an OrientDB database on a CentOS 7 Hyper-V VM. The VM has 4 Cores and 4 GB RAM.

My problem is, that the OrientDB Java process stops unexpectedly and I can't find the problem because I can't find any error logs.

I've already checked the kernel logs (/var/log/messages), dmesg (/var/log/dmesg), journalctl and the OrientDB logs. None of these logs show me any errors.

I have the dull feeling that there is some OOM problem, but I can't find any proof for it. Also, top tells me that there should be enough memory and as long as I am monitoring the VM, memory consumption seams to be fine.

So, can anybody give me some advice where I can get hints what happened to the Java process? There is also a Tomcat running (also a Java process) without any problems.

Answer 1

please update to 2.2.20 fix. I suppose that your problems are caused by the bug (direct memory leak) which we have fixed in given release.
