Default Found Factors not recognised by server

About 2 weeks ago I upgraded my linux os on one of my pc and from then on primenet has stopped recognising any factors my pc finds. When I factor a LMH number to 65 bits, and find no factor, the server accepts this, but if I find a factor, the server says that the number is still assigned to me with no factor, and the number having been factored to 64 bits.

I have attached the edited part of my results.txt file with the found factors results.

Most of these haven't been credited or aknowledged by the server.

Why has this happened?

TIa.

Hardware problems??

I tried submitting one of your factors manually:

Processing result: M115146271 has a factor: 34214208965692228777, AID: E5D25CC598D9B837AE8B81D564FEC647
Error code: 45, error text: 34214208965692228777 is not a factor of M115146271

See here. The problem persists, at least for me.

Hey prime95, I checked my personal results and noticed the manual test, and it was a FACTOR. I then did a status check on the exponent and found this, 115146271 Factored 34214208965692628777 So The Error message means that primenet is not accepting LEGITIMATE factors. I'm runing mprime 25.11 64 bit version of Ubuntu 10.04 64 bit. I'm sure the other factors in that list are legit too, my system (cpu) is rock solid, no overclocking, and i do alot of cideo encoding and haven't had any problems, also this problem only occured after the upgrade to ubuntu 10.04. Any suggestion?

Notice your results.txt lists the factor as "...2228777" whereas axn corrected the factor to "...2628777".

The link ckdo pointed to shows that this is a Ubuntu problem. Most likely in the C runtime library. I agree your hardware is OK.

I'll need to install the latest Ubuntu on one of my boxes here to debug the problem. Things are kind of busy right now, so it may take awhile before I can fix it.

In the meantime, perhaps axn will volunteer to correct the factors and credit them??

I wonder if this is related to the problem we have seen with 64-bit PFGW on Linux. It is a problem that I haven't seen with 64-bit builds on Mac or Windows.

Done. If OP can verify that these show up under his account...

Thanks axn, I checked my account, and a whole bunch of manual testing results have been credited, all FACTORS. Thanks very much. Should I just Post my results.txt file here every week to have the factors credited, until the problem is fixed?

For now, sure. But ideal would be a script that can directly parse the results.txt and generate the corrected lines for submission. Unfortunately, my linux script-fu is weak.

There is definitely a bug in the gcc 4.4.3 compiler on Ubuntu. When I build a 64-bit PFGW with optimizations, gwnum fails miserably on sum numbers, but without any optimizations (-O), it works correctly. This same 64-bit PFGW works correctly both with and without optimizations on MacIntel and Windows.
