Set the message size limit on the Router or Message Processor

Edge for Private Cloud v4.18.05

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:

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
```

Set the properties as desired:

conf_http_HTTPRequest.body.buffer.limit=15m
conf_http_HTTPResponse.body.buffer.limit=15m

Save your changes.

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

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
