Congratulations boss, very nice. In at #18
Glad someone found one. Happens too many times no prime is found during a challenge.
But at least we know where not to look anymore!

Thanks for the responses. Obviously this is disappointing! But good to know.

New warnings when LLR2 detects Gerbicz errors

There is an opportunity suggested here to create a tool that is very sensitive to computer stability. During the run-up to the current challenge, I noticed these "Gerbicz errors" in one of the output logs on a Ryzen 3700X, while testing an offline WU, but only with certain task/thread combinations, notably 8 tasks of 2 threads. The problem is yet unresolved, but for now running 8 tasks/1 thread works, and also provides slightly higher throughput. So even though this PC is not overclocked, and can run Memtest all night with no errors, it has a problem!

Max FFT size for each LLR project?

Hi,
There seems to be a bit of disagreement in regards to calculating the approximate L3 footprint of the various PG WUs. The difference between multiplying by 8 or 24 is pretty large! Is there a reason why 8x seems to work in practical terms when 24x appears to be the theoretical answer?
