Hi all
after running ES ver 90.2 for weeks, the status changed to red. and here is
my cluster health:
{
cluster\_name: Meteorites
status: red
timed\_out: false
number\_of\_nodes: 1
number\_of\_data\_nodes: 1
active\_primary\_shards: 96
active\_shards: 96
relocating\_shards: 0
initializing\_shards: 0
unassigned\_shards: 114
}
and here is my cluster nodes status:
{
ok: true
cluster\_name: Meteorites
nodes: {
QDVMZqGCS0Cd2GKic7PtWw: {
name: Meteorite01
transport\_address: inet[/192.168.1.45:9300]
version: 0.90.2
http\_address: inet[/192.168.1.45:9200]
attributes: {
master: true
}
}
}
}
and last lines of my logs:

Hello Iman,
Try checking if you're hitting the limit on the number of open files. By
increasing the open files limit 🙂 The way you're doing that depends on how
you installed ES. But here's a nice tutorial about it:

> Power insights and outcomes with The Elastic Search AI Platform. See into your data and find answers that matter with enterprise solutions designed to help you accelerate time to insight. Try Elastic ...
I'm not sure if this is the cause, but just searching around this error: "
IOException[directory XXX exists and is a directory, but cannot be listed:
list() returned null", returns a lot of "too many open files" associations.
## Best regards, Radu
