Default MD5 mismatch - Unexpected error during p110825543.proof.tmp upload:

I was, up to a few minutes ago, performing PRP tests on 110825543 and 33264623 with mprime Linux64,v30.3,build 6. I am using a Dell 7920 with 2 x Intel Xeons 8167M with 320 GB of error correcting RAM. The operating system is CentOS 7.9. The latter exponent, which is only 47.48% complete and has 12 days to go. (That's the first and last time I attempt a 100 million digit exponent). However, the former

https://www.mersenne.org/report_expo...0825543&full=1

has just completed, but with an error message.
Code:

(See a bigger section of the log I keep below. The assignment was allocated to me, and is shown as completed, but not prime. I chanced my username on here, as I think that's supposed to be private, although personally I have no problems with anyone knowing it.

The certificate eventually got uploaded, and the result verified by someone using the certificate.

https://www.mersenne.org/report_expo...0825543&full=1
The only problem I noticed is that there are two 14 MB files left over
m110825543 m110825543.bu
I will just delete them. So the problem has been resolved.

Apparently someone at Microsoft thought it would be really cool if FindFirstFile returns xxx.proof.tmp when asking for all file names matching *.proof

In the Tomb of the Unknown Implementor...

Upon entering the tomb, one is greeted by a hollow voice that says, "That's not a bug, it's a feature!"

As stated in the original post, I was running CentOS 7.9 - i.e. Linux, so as much as I do like to bash Microsoft over Windoze, it's difficult to blame M$ here.

Might have to bash me, off to check the Linux code....

Yup, mea culpa, as Chris likes to say "stupid programmer error".

Okay, consider yourself bashed to look at the linux code. Could I suggest two more things that could do with improving.

1) When it says "uploading binary data" or something like that, it would be good to know what is being uploaded. I see some messages later in the day about uploading the binary data, but did not know if they were the proof file or not.

2) I can set the Daytime P-1/ECM stage 2 memory to 100 GB, and the Nighttime P-1/ECM stage 2 memory to 100 GB, However, I'm limited to setting the maximum emergency limit to a lower figure of 78.582520 GB which does not make any sense to me. How can the emergency limit be lower the non-emergency limit?
Code:
Daytime P-1/ECM stage 2 memory in GB (100.000000):
Nighttime P-1/ECM stage 2 memory in GB (100.000000):
Max emergency memory in GB/worker (70.000000): 120
Please enter a value between 0.000000 and 78.582520.

Regarding 2)
These are memory settings for totally different things. The first two (as indicated) are only used in stage 2 of P-1 and ECM. The third one is memory reserved for temporary unavailable file writes, i.e. if you save your proof files to a network share and it's disconnected in the moment the proof gets written, it will be stored in the emergency memory until the network share is reconnected.
