- Ubuntu 18.04
- Neo4j: 3.5.3, Browser 3.2.16
- Python driver
- Algo's plugin
- Due to numerous " Discarded stale query from the query cache after n seconds" the logs are littered with personal data
So I've been trying to start using Neo4J in a project, but have struggled to keep it stable and the server available for the passed few weeks. I am running the server within a VM running on ESXi, 8 vCPUs, and 6gb of ram, should be plenty from my understanding.
Seemingly unprovoked, the database goes unresponsive, and the whole OS locks up; the server can be idling, running queries via the python driver/dashboard, or even just trying to authorize a user via the dashboard. Open SSH sessions to the VM are left hanging, as well as the console view via the hypervisor. A full VM reset is required to regain access.
At first I was trying to user the version available through debian repositories, but ran into the stability issues and decided to download the provided tar and run it that way. The issues persisted. Next I tried pinning the VM memory figuring memory sharing may be at fault, but again no dice. Eventually I went into the DB configs and increased the memory to the max the VM has to spare but again, the problem persisted. That leaves me here, I'm really not too sure what to do, but have been enjoying the system while it does work but am frustrated.
The logs do not seem to show anything meaningful in the terms of the crashes, everything seems to hang silently as far as I can tell. I will try to start removing PII from them and post them but thought I would ask first.
Thanks for any help in advanced
