Hi everyone,
I'm dealing with a problem on Elasticsearch 7.17.5 (I've also tried to upgrade it to version 8 but I'm having the same problem with that version too) which is hanged, red status and unresponsive on any write request (for example POST and DELETE calls).
I tried to enlarge the Java heap size, restarting the server many times, with no success.
This is the _cluster/health
output:
{
"cluster_name": "my_elastic_cluster",
"status": "red",
"timed_out": false,
"number_of_nodes": 1,
"number_of_data_nodes": 1,
"active_primary_shards": 234,
"active_shards": 234,
"relocating_shards": 0,
"initializing_shards": 1,
"unassigned_shards": 125,
"delayed_unassigned_shards": 0,
"number_of_pending_tasks": 252,
"number_of_in_flight_fetch": 0,
"task_max_waiting_in_queue_millis": 26331,
"active_shards_percent_as_number": 65
}
Here you can find some information and logs:

Could you help me to find out what's going on, and how to resume this server without loosing data, please?
Thank you very much!
Bye
