How to diagnose hashcat progress stalling? - serious-business - 07-20-2025
I'm on an Intel MacBook Pro with AMD GPU and running hashcat v6.2.6-1259, built from source. It was eventually able to crack a real-world WPA2 hash, but instead of taking ~2 hours as estimated, it took a couple days. Hashcat would be making great progress, and then, suddenly, progress percentage would stop increasing, fans would slow down, and GPU utilization (? Hardware.Mon.#01 & #02.: Util) would drop to 0%
Even leaving hashcat alone overnight, it did not start making progress again. The abort trigger temp was not exceeded, the battery did not get low, and I prevented the MacBook from going to sleep. Eventually, I started checkpointing every 10–20%, but sometimes hashcat would stall after the request, and I'd have to quit, restore, and try again. I think it finally recovered the password at 78% from a restore point of around 60%.
The initial command I used was
Code:
hashcat --session name -D 2,1 -d 1,2 -m 22000 hash.hc22000 -a 6 dict.txt ?maskI am now working on a different hash, which again has a reasonable estimated time to completion, but hashcat is again dying on me. I requested a checkpoint at 10%, and it kept going rapidly until 19.42%, but now it's stopped. ps says the process is in uninterruptible wait.
What other possibilities are there for what's going on, or where can I find additional clues? Is there something I should look for in the session log file?
