Specifies the memory level at which blocking memory allocation requests are put to sleep, even if the memory is sufficient to satisfy the request.
Unsigned integer
minfree
The minimum value is 128 Kbytes or 1/256th of physical memory, whichever is greater, expressed as pages using the page size returned by getpagesize.
The maximum value is the number of physical memory pages. The maximum value should be no more than 4 percent of physical memory. The system does not enforce this range other than that described in the Validation section.
Pages
Yes, unless dynamic reconfiguration operations that add or delete memory occur. At that point, the value is reset to the value provided in the /etc/system file or calculated from the new physical memory value.
If throttlefree is greater than desfree, throttlefree is set to minfree. No message is displayed.
The relationship of lotsfree is greater than desfree, which is greater than minfree, should be maintained at all times.
The default value is generally adequate. For systems with relatively static workloads and large amounts of memory, lower this value. The minimum acceptable value is 128 Kbytes, expressed as pages using the page size returned by getpagesize. For more information, see getpagesize(3C).
