max_stat_memory

Specifies the maximum amount of memory to use for detailed statistic gathering.

max_stat_memory = size [KB|MB|GB]

If no units are specified, the amount is in bytes, otherwise you can specify the amount using KB, MB, or GB as the units.

Once the maximum memory limit is reached, the server stops collecting detailed statistics. If statistics are deleted and memory becomes available, the server resumes detailed statistic gathering.
