If it's of any help ewmayer, GPU72 has a similar issue with one of it's spiders. My hack is to have a slaved mprime with the same CID contact Primenet once a day saying "Hi. I'm still here."

Not sure if this could be easily implemented in a wider deployment scenario. Probably better to figure out how to talk to the API with untrusted code. Perhaps limit any database deltas possible to be solely the last contact date -- no security exposure, and would solve your problem more gracefully.

I have a largish perl script in development and daily use, that among other actions, gathers new results from however many gpu app instances it's configured for, on a system, into one file. Currently that is manually submitted by me. It handles the most common versions of the BIG SIX gpu apps: cllucas cudalucas cudapm1 gpuowl mfaktc mfakto. Each app instance's results may have configured in its ini files or batch file a different compound UID/CID combo, unique per system/gpu/app-instancecount, for full traceability back to the result's origin. So for example, Kriesel/condor-gtx1060-2 identifies the TF result as coming from the second instance/folder for the gtx1060 on system condor. TF throughput is higher with multiple instances, so on some gpus where the percentage gain is sufficient in my opinion, which tends to be cards gtx 480 or 1060 and faster, I run 2 or sometimes 3 instances in parallel. Now multiply that by several systems equipped with gpus (mostly multiple) and with multiple app types. Manual reporting lumps them all into a single manual bin which has no corresponding cpu or mprime/prime95 instance or CID. That bin contains the great majority of all my results, at 72% of the total currently.
I would like to be able to interface the script to PrimeNet eventually, and make it available to others to use, including with precompiled executables (which I have working now for my own local distribution for test to multiple systems some of which do not have perl installed).

It sounds like the PrimeNet API is not currently well suited to gpu support or to untrusted-app support.
Both EWMayer and Preda have grappled with it and turned back.

For me, this was, as far as I know, a legit unexpired first-test PRP assignment. But I suppose it's possible my assignment expired along the way.
The same as with me, no poaching, only early double check, but my old hardware still seems to be working fine.

Yup. We're going to see the next MP much sooner than originally guessed...

We all have the same success count over the past year.
We could be in a barren stretch of the number line. The presumed Poisson distribution has already had ratios of successive exponents of Mersenne primes of ~4:1.. Even the mean expectation, of ~1.47:1 on exponent, implies ~121M, or tens of millions of exponent range to go. A 4:1 puts us near 100Mdigit range. GIMPS has had a very lucky run. Play long enough, and the house wins. The best conjectures indicate there are about 6 more Mersenne primes to find in the range below p=109, which under reasonable assumptions will take generations to fully first-time test.

Welcome to statistics. It has no memory...

And, this doesn't counter my argument. Thanks to Ben, we're going to find the next MP much sooner than originally projected.

Soon or sooner seem misused, in a context that may involve a desired event per generation. Less unbearably slow perhaps.
The work to primality test up to a given exponent p from 2 is with the best available algorithms, around p3 to p3.1. That eats up powers of 2 or ten on throughput quite readily. LL/LLDC phaseout and PRP DC replacement with the much more economical proof and verification provides nearly 2:1. There are some small gains possible in TF and P-1.
(For a while I'd post such pessimistic comments, and shortly seem to be shown wrong by a new prime find. No such luck lately.)

I wonder how long Ben will continue what is probably a massive financial donation to the cause.

At my current rate I predict a 10-20% chance per year of finding a MP.

There may be no more Mp's to be had. So it is possible that he hasn't helped at all.

I have a vague recollection of someone expressing in the mailing list, pre-forum, that no more than 37 Mersenne primes would ever be found, since that was how many existed. It seemed to be some sort of religious belief, or an artful troll pretending to be such. One hopes he changed his mind based on evidence. And not to the belief that no more than 51 or perhaps 53 will ever be found.
Contrast with the Lenstra-Pomerance-Wagstaff conjecture.
