Subject: excessive memory usage when running john - 90 gigabytes

I am running john-1.9.0-jumbo-1-win64 on a windows 10 pro computer.
The computer has 128gb of ram and an amd epyc processor with 16 cores 
and 32 threads.
I am currently trying to find 4 descrypt passwords with john.

When I run john, and looking at the task manager performance tab, the 
system is using 99.3 gigabytes of memory.
When i stop john, the system is using about 8gb or memory.
The task manager process view tab shows john using 65.0 megabytes of memory.

I am quite curious what part of john is using 90 gigabytes of ram, and 
why it is using so much memory.

Thanks in advance,
jeff
