Hi, I'm having problem with my elasticsearch running server. At the beginning it was working fine, when I needed to update Data. But suddenly after trying to update several files at once (5 files), the system is performing poorly, taking more than 7 or 8 hours to process a file, when previously is was 1 hour. Also, the performance problem has reached Kibana (it takes 2 minutes to load the main page with date and previously it was less than a second). I think the problem is because of the heap ( which is configured as -Xms2g -Xmx8g) and, for example, Kibana is using 99%. I tried to delete all the indices from the node and the problem persist.
I tried to set up bootstrap.mlockall: true, but the server that's allow it (Unable to lock JVM Memory: error=12,reason=Cannot allocate memory).
The server has 8GB of RAM.
This is the current status of the health state cluster:
