Vision allocates a memory buffer for each file opened for bulk addition. The
size of this buffer is controlled by the V_BULK_MEMORY configuration option. The default size of this buffer is 1 MB.
Note that the default size is fairly large because it is assumed that only a
few files will be open for bulk addition on a system at any one time. If this
buffer cannot be allocated, the OPEN fails with a status indicating inadequate
memory.
To change the size of the allocated memory buffer to, for example, 500 KB, you
would enter:
V_BULK_MEMORY = 500 KB
