Group_Max_Buffer

The Group_Max_Buffer option specifies the maximum number of bytes of data that are allowed to be buffered to each group connection (such as the one used by RTgms—the multicast publishing process). This maximum buffer size is used to check for possible network failures. To prevent a large backlog from consuming all available process memory, RTserver limits the buffer size of each group connection to Group_Max_Buffer bytes of data; if a group connection (such as a connection from RTgms) consumes too slowly, so that the buffer grows beyond this limit, then RTserver destroys the connection.

This option is required and cannot be unset.
