# Solving common errors
|
|
|
|
## Too many files open (OS error 24)
|
|
|
|
Each collection segment needs some files to be open. At some point you may encounter the following errors in your server log:
|
|
|
|
```text
|
|
Error: Too many files open (OS error 24)
|
|
```
|
|
|
|
In such a case you may need to increase the limit of the open files. It might be done, for example, while you launch the Docker container:
|
|
|
|
```bash
|
|
docker run --ulimit nofile=10000:10000 qdrant/qdrant:latest
|
|
```
|
|
|
|
The command above will set both soft and hard limits to `10000`.
|
|
|
|
If you are not using Docker, the following command will change the limit for the current user session:
|
|
|
|
```bash
|
|
ulimit -n 10000
|
|
```
|
|
|
|
Please note, the command should be executed before you run Qdrant server.
|
|
|
|
## Can't open Collections meta Wal
|
|
|
|
When starting a Qdrant instance as part of a distributed deployment, you may
|
|
come across an error message similar to this:
|
|
|
|
```bash
|
|
Can't open Collections meta Wal: Os { code: 11, kind: WouldBlock, message: "Resource temporarily unavailable" }
|
|
```
|
|
|
|
It means that Qdrant cannot start because a collection cannot be loaded. Its
|
|
associated [WAL](/documentation/concepts/storage/#versioning) files are currently
|
|
unavailable, likely because the same files are already being used by another
|
|
Qdrant instance.
|
|
|
|
Each node must have their own separate storage directory, volume or mount.
|
|
|
|
The formed cluster will take care of sharing all data with each node, putting it
|
|
all in the correct places for you. If using Kubernetes, each node must have
|
|
their own volume. If using Docker, each node must have their own storage mount
|
|
or volume. If using Qdrant directly, each node must have their own storage
|
|
directory.
