Kibana Crash while loading index list

Elastic Stack Kibana
1

Hello,

I have an ELK Cluster of 3M+12D nodes , with 64GB and 8 cores for the data nodes and a total of 53 TB of data, 3243 indices, 7602 shards. On top, i have a Kibana instance of 8GB RAM + 4 CPU. Both Kibana and ELK are at 7.17.2 version.
From Kibana when i try to go to Stack Management -> Index Management -> Indices while i wait for the index list to be loaded, kibana service crashes with the following message in service logs:

Is there a limitation in how many indices can be listed into the Kibana UI?
Did anyone else encountered this issue and can help?

Thanks!

FWIW 7.12 is EOL and no longer supported, you should be looking to upgrade as a matter of urgency. Also it looks like your average shard size is about 6-7GB, which is pretty small and you are likely wasting some resources with that.

To your question - I haven't seen this before, but the first and best option is to upgrade to 7.17 to see if that helps.
