Unable to publish messages with larger payload sizes about server HOT 4 CLOSED

I think the next step should be adding parameters to server allowing the operator to modify the buffer sizes. I'll try to get a PR done for this in the coming week and we can add it to v1.2.0.

(I wonder what happens if a single request exceeds the size of the circular buffer.)

The default buffer size is 1024 * 256 (262,144 bytes). There is capacity in EstablishConnection to set this value (currently hardcoded 0 to use default), but it hasn't been opened to allow a custom value as yet.

@deadprogram I would be interested to know what happens if you increase the size of the following values:

If increasing the buffer size allows it to successfully work, we should implement a parameter to adjust this value, and potentially increase the default size.

Thanks for the quick response. I just tried increasing both of those values, and it did indeed resolve that problem.

From a brief reading of the code seems like server.New() is where the buffer size needs to be able to be changed from the default value.

So what is the best way to proceed from here?
