*Edge for Private Cloud v4.19.01*

To prevent memory issues in Edge, message payload size on the Router and Message Processor is
restricted to 10MB. Exceeding those sizes results in
a `protocol.http.TooBigBody` error.

Use the following properties to change the limits on the Router, Message Processor, or both.
Both properties have a default value of "10m" corresponding to 10MB:

- `conf_http_HTTPRequest.body.buffer.limit`
- `conf_http_HTTPResponse.body.buffer.limit`

To set these properties:

1. Open the `router.properties` file or `message-processor.properties` file in an editor. If the file does not exist, create it:

   ```
   vi /opt/apigee/customer/application/router.properties
   ```

   or:

   ```
   vi /opt/apigee/customer/application/message-processor.properties
   ```
2. Set the properties as desired:

   ```
   conf_http_HTTPRequest.body.buffer.limit=15m
   conf_http_HTTPResponse.body.buffer.limit=15m
   ```
3. Save your changes.
4. Make sure the properties file is owned by the "apigee" user:  

   ```
   chown apigee:apigee /opt/apigee/customer/application/router.properties
   ```

   or:

   ```
   chown apigee:apigee /opt/apigee/customer/application/message-processor.properties
   ```
5. Restart the Edge component:

   ```
   /opt/apigee/apigee-service/bin/apigee-service edge-router restart
   ```

   or:

   ```
   /opt/apigee/apigee-service/bin/apigee-service edge-message-processor restart
   ```
