Statistics history can now be automatically made smaller if a systems memory resources are above a certain amount. By default
this is enabled and will trigger when over 95% of memory is in use. Half of all existing entries will be removed at this time.
The same pattern will continue to halve the available records every time the threshold is met. A hard-set minimum of 5 entries
is set, so you will always have the last 5 entries.
This setting may be adjusted by adding the following setting to your config.tdsl file and adjusting the integer value:
stats() {
'stats-high-memory-level' = 95
}
