Amount of messages that can enqueued in order to be processed by shell thread. Too small queue may lead to logger thread being blocked (see $(module)_LOG_MESSAGE_QUEUE_TIMEOUT). Too big queue on relatively slow shell transport may lead to situation where logs are dropped because all log messages are enqueued.
