This configuration value sets the maximum amount of memory this STREAMS subsystem is allowed to allocate for its buffers, queues, and other internal structures for the STREAMS I/O subsystem on this host. The source MIB's own DESCRIPTION for this object is only the placeholder text "T B S" (to be supplied), so this reading is inferred from the object's name, its position in the STREAMS admin table (whose table-level DESCRIPTION says it holds "configuration information for a STREAMS subsystem"), and its Integer32 syntax; administrators raise it if the subsystem is running out of resources under heavy load, or lower it to cap how much memory STREAMS can consume.
