Max. number of subsequent asynchronous requests
Some requests to the enqueue server take place asynchronously; thismeans the system does not wait for a response from the server. If theserequests are sent in too rapid a sequence, this can lead to an overflowin the communication buffer, which means requests might be lost. Toprevent this happening, a synchronous request is forced every nasynchronous request. You specify this number n in this parameter.
