Subject: problem running out of memory - john 20240608.1
I am using Bleeding john 20240608.1
I have quite a lot of NTLM hashes. I have broken them up into files of
about 1 gigabyte each.
I start up john:
K:\password-cracking\john_bleeding_2024_0608.1\run>john.exe --format=LM
--fork=60 \password-cracking\pwnedpasswords_ntlm.rawest.xaa
Using default input encoding: UTF-8
Using default target encoding: CP850
Loaded 62433618 password hashes with no different salts (LM [DES 256/256
AVX2])
Will run 2 OpenMP threads per process (120 total across 60 processes)
Node numbers 1-60 of 60 (fork)

Disabling duplicate candidate password suppressor
This is on a microsoft winfows 10 system. I am watching the task
manager, and the memory usage goes to about 110gbytes (I have 128gbytes
of ram).
This is on a 64 core AMD epyc milan system.
If I need to break up the password file into smaller sections, I can do
that. I tried files of about 300 mbytes and that also seemed to run out
of memory.
Please help me find a path forward. I have a total of about 30 gigabytes
of NTLM hashes I wish to process.
