max_client_msg_size
Maximum size allowed for an incoming message. This parameter setting instructs the server to reject incoming messages that are larger than the specified size limit.
max_client_msg_size = size [KB|MB|GB]
Specify whole numbers as
KB,
MB or
GB. The maximum value is 2 GB. However, we recommend that the application programs use smaller messages, since messages approaching this maximum size will strain the performance limits of most current hardware and operating system platforms.
When omitted or zero, the EMS server accepts and attempts to process messages of any size.
