> In the code below, {{this.maxQueueSize = queueSizePerHandler;}} should be
> {{ this.maxQueueSize = handlerCount * queueSizePerHandler;}}. Luckily, I
> search the code base and found most callers invoke the constructor with
> queueSizePerHandler=-1. This ticket is opened to make it correct for the case
> when queueSizePerHandler is not -1.
> {code}
> if (queueSizePerHandler != -1) {
> this.maxQueueSize = queueSizePerHandler;
> } else {
> this.maxQueueSize = handlerCount * conf.getInt(
> CommonConfigurationKeys.IPC_SERVER_HANDLER_QUEUE_SIZE_KEY,
> CommonConfigurationKeys.IPC_SERVER_HANDLER_QUEUE_SIZE_DEFAULT);
>
> }
> {code}
