I am using ELK 7.12.1 and Kibana 7.12.1 in a production env. I am encountering an issue with my Kibana , the process keeps crashing. The app is hosted on 1 VM , having 8 GB of RAM.
At first i did not do any modifications to the allocated heap memory, so it had standard 2 GB. After some crashes, i also increased the heap to 4 GB which temporarily fixed the issue for a few days. What i observed in the monitoring graphs is that it increases memory usage until max(8GB) and the process crashes. What is strange is that i don't have anything relevant in the logs, not even the OOM.
What could be consuming so much memory?
Did anyone encountered this type of issue?
