# ERR max field size exceeded

### Symptom

The client gets an exception similar to:

```
ReplyError: ERR max field size exceeded. Limit: X bytes, Actual: Z bytes
```

### Diagnosis

Size of a HASH field in the request exceeds the max field size limit, which is
`32Kb`.

### Solution

This is a hardcoded limit and cannot be configured per database. You should
reduce the field sizes in HASH entries.
