I have created a Weaviate Setup in AWS ECS and create auto-scaling. Due to spike load, the weaviate instance restarted and now, I am getting below error which accessing the data.

{  
“data”: {  
“Get”: {  
“WeaviateDemo3”: null  
}  
},  
“errors”: [  
{  
“locations”: [  
{  
“column”: 6,  
“line”: 1  
}  
],  
“message”: “explorer: list class: search: object search at index weaviatedemo3: local shard object search weaviatedemo3\_PXksOv6syq7H: Unable to load shard PXksOv6syq7H: init shard “weaviatedemo3\_PXksOv6syq7H”: init shard “weaviatedemo3\_PXksOv6syq7H”: shard db: create objects bucket: init disk segments: init segment segment-1719829104648996364.db: mmap file: invalid argument”,  
“path”: [  
“Get”,  
“WeaviateDemo3”  
]  
}  
]

- Weaviate Server Version: 1.24.4
- Multi Node? Number of Running Nodes: Single Node only
- Client Language and Version: Python
- Multitenancy?: No

We are persisting data in AWS EFS and we face this issue as soon as the instance reboots.

HI @saurbhhsharrma !!

I have seen a similar error 🤔

Can you check if that file `1719829104648996364.db` is empty?

This may also be a symptom of reaching the limits of the hardware, so time to a multi node deployment.

How many objects are you running?

Also, check here for a similar thread:

> Hi @msj242, this error init segment segment-1705570724834516877.db: mmap file: invalid argument" may be caused by a corrupted .db file, it could be due to a reboot or unexpected crash (also during compaction) when using a version lower than v1.24 where integrity of files was improved. Was that data created in an older version?
