# ERR DB capacity quota exceeded

### Symptom

The client gets an exception similar to:

```
ReplyError: ERR DB capacity quota exceeded
```

### Diagnosis

Your total database size exceeds the max data size limit, which is `256Mb` for
"Free" and `10Gb` for "Pay as you go" databases. When this limit is reached,
write requests may be rejected. Read and delete requests will not be affected.

### Solution-1

You can manually delete some entries to allow further writes. Additionally you
can consider setting TTL (expiration time) for your keys or enable
[eviction](../features/eviction) for your database.

### Solution-2

You can upgrade your database to Pro/Enterprise for higher limits.
